Are you installing bbPress as a plugin under your WordPress?

[collmonster]

Hello.

I just installed the bbpress to my wordpress site. I was just setting it up, and int he settings it had a line where you could set the url of the install. I mistakenly thought I could use this to change it to a shorter version.

I was on: http://www.mydomain.com/wp-content/plugins/bbpress/bb-admin/ (I think)

and I changed to http://www.mydomain.com/forum

Now its broken. All I get is a 404 page from my wordpress site.

I tried deleting and reinstalling but it won’t work!

Any idea how I can fix this?

Please help!!!

Thanks

I’m having trouble integrating logins for WordPress, Buddypress and bbpress. I have done so for WordPress and Buddypress, but when I installed bbpress last, and followed the instructions in this video: http://dotsub.com/view/7cb6fb61-2fa0-4d6d-a090-257b0be87a50 it still didn’t work. Please help! thanks!

We’ve carried out the install and all is working well – http://piedpiper.org.nz

Thank you for a great product

I’m wondering if I can use BBpress as a “blog” with the latest “articles” showing up as the “Latest posts” do here in BBpress.

So can I set up BBpress set to have a Navigation bar along the top with typical “About us” pages, “How you can help”, etc? (The usual top 5 to 10 pages you have on blog or introduction to your website etc). Any other ideas?

Then everything else can just be in the forums.

Also, because BBpress is a VERY stripped back forum with lots of plugins, does the plugin for email notifying still work? (Getting an email any time someone replies). Can I set ALL users to getting that?

Can I as the Admin set the “Tags/categories” that posters can then select from?

Is there an auto-backup plugin of some sort? (I hate database stuff).

What else do I need to install to use BBpress as my main community portal / blog (without wordpress).

[mothership]

We’re about to install and integrate bbpress with an existing WordPress installation. We put the WordPress files in a ‘wordpress’ subdirectory when installing to keep the httdocs directory clean. Will this affect integration in any way? If need be, we can move this back.

Ideally, we would like to have WordPress in a /wordpress directory and bbpress in a /forum directory with WordPress accessible via the root, and bbpress via /forum.

Also, on a slightly different note; how have people found integration with 1.0.2 and 2.8.4?

[mpesgt01]

If we use bbPress as a forum… and WordPress as a blog… and that we can add a way that the members can upload photos to their own profile… we would then almost get a social software/php script and that would be awsome !!!

I am not a coder (i’m a web designer) but I do know that it can be possible to create this plug in.

I just saw your next look, the bbpress 2.0 and with that plugin, a profile album, it would be it !!

Than maybe later another plugin for same thing, but videos (either upload or grab via youtube), but this can be invented later… photos first !!

Any chances ???

I’d be lazy and take something like Tom (db)’s WPNews and flip it around

For RSS, you can google around for solutions. I’m not sure there are any bb specific ones.

Hi!

I always have problem with the integration of BBpress and WordPress, i have installed bbpress integration in wordpress and stuff but still it doesnt work!

The cookies kinda works, when i login to WP i get loggedout of BBpress and vice versa!

Is it because i install it on localhost or something?

Couple of pictures, can anyone spot whats wrong?

I really appreciate some feedback!

I’ve discovered that several of my plugins that have admin menus will not be able to access the admin menu in bbPress 0.9.0.7 and 1.0.3 because of the new admin menu security lockdown that was merged from WordPress 2.8.3 (essentially I didn’t go through the API for bbPress 0.8 compatibility).

I’ve now fixed what I can find but there will be other plugins with the same problem.

I highly recommend people learn how to install bbPress (and wordpress) via SVN, it makes life incredibly easy. You can switch between bbPress versions in a heartbeat, test new betas or jump back to the previous version effortlessly.

See this topic for more info:

https://bbpress.org/forums/topic/svn-procedure-for-checking-out-bbpress

and my note at the end on how to install SVN as a simple client instead of the whole darn thing.

[gerikg]

Did you….

-have the Cookies & Salt all the same? example BBpress side define('BB_AUTH_KEY', 'ABCDEF'); WordPress side define('AUTH_KEY', 'ABCDEF');

-include $bb->bb_xmlrpc_allow_user_switching = true; in bb-config.php before the ?>

-install BBpress intergration plugin to get the Hash and cookie information to paste in wp-config.php after the < ?php ?

-Paste the same cookie information you did on the step before in bb-config.php (without the Hash line) after the < ?php ?

-Enable Pinbacks, trackbacks, and XML-RPC on BOTH WPMU & BBpress?

[johnhiler]

You definitely want to use the same users table for both installs.

I’ve had to eventually integrate bbPress and WordPress users after not integrating them upfront, and you definitely want to do it sooner rather than later. It wasn’t fun, but it’s definitely doable.

There’s a good discussion on how to go about it here:

https://bbpress.org/forums/topic/integration-of-established-wp-and-bbpress-installations

I eventually wish to use BuddyPress on a site, but feel I need to do this is stages.

At the moment this site consists of WordPress on one database and BBPress on a different database using the most recent versions of both scripts.

I started integration but stopped because I saw a potential problem.

I have about 70 registered users on BBPress

I have about 10 users on WordPress, these are mostly Authors.

I gave the users the same rank on both, making the WordPress Authors, Moderators on BBPress

Still, I suspect that I could be making a huge mistake if I don’t merge the User tables before integrating, and of course I would want everything setup correctly for interrogation before playing around with MU and BuddyPress.

Now if I understand this correctly the User table for an integrated site should be WordPress, not BBPress?

Is there such a thing as a script that would allow me to make all BBPress users WordPress users?

Or am I looking at this all wrong?

Or is it possible to set up MU/BuddyPress and merge all users onto that?

I think you may be confused _ck_. memcache has it’s uses like php op_code. It does not take alot for it to have a benefit and the same applies to memcache. However I am not asking for a suggestion on avoiding memcache. I would like to see a better handling of objects in the same way you create a prefix for a database. If you set a large pool for memcache say 1gb. The idea of setting another instance and monitoring it with startup script gets a little bothersome especially when an array can be used to mitigate the possibility of one failed instance to drive your site down. In short I should say you don’t usually start another mysql to house a database nor would it be useful to do that with memcache.

Thanks samhaurs again. I just want to be sure there weren’t objects that are generically named that can be seen across bbpress installations like administrative or personal details that should be separate that some are improperly written to cache much like wordpress mu does at the moment.

[Sam Bauers]

“[WordPress.com] uses several dozen queries per page load.”

Thanks to memcache the average blog front page on WordPress.com uses only a handful of queries, sometimes as few as one.

“It absolutely cannot just rely on the mysql cache, even with dedicated mysql servers.”

From memory, WordPress.com doesn’t use MySQL query cache at all as it would need to be invalidated many times every second. We also would need to invalidate all slaves as well as the masters.

I think it’s important to say that you should only setup and enable any caching if you actually need it. Most people don’t and shouldn’t, all you do is add another potential point of failure into your site.

[_ck_]

Let’s review this from scratch.

WordPress and bbPress 1.0 has what we call an object cache. That is simply a pool of users, forums,topics, and posts and meta as they are passed between mysql and the application (wordpress/bbpress). It’s just another layer between mysql and bbpress.

Typically these “objects” are lost after every page load because they are no longer in regular short-term computer memory and have to be fetched again from mysql.

On a single computer system with a fast mysql server and fast disk cache, this typically is not a big problem. As a site has to scale this does become a problem because there is only one mysql source and everything has to be fetched from it.

Using a poorly configured WordPress or bbPress system with badly written or improperly running plugins, if each page load requires 30-40 queries, and you have 1000 users connected simultaneously at once, that’s a huge problem.

Memcache is a common pool of memory that doesn’t go away after each page load. It’s centralized on one server so multiple servers can all find it easily. It was invented by LiveJournal after they hit a growth limit with mysql.

The Memcache to Object Cache interface plugin for WordPress/bbPress 1.0 allows the fetching from mysql to be skipped IF the user/forum/topic/posts happen to be in the previously accessed pool in that centralized memory. Every time a query is made, the resulting data is saved in the collective memory which is retained inbetween page loads. It’s a common, shared memory.

However Memcache was written to talk over tcp/ip between MULTIPLE servers. For a single server setup it’s pointless and stupid and way too much overhead.

Now, on a single server, you could still use a persistent object cache with one of the other lesser known plugins that mimic what the memcache interface does. There is one for Eaccelerator, one for APC and one for Xcache.

However, all of these caches do almost the same thing as MySQL’s cache. They are all tied to the particular kind of query that is done and if it matches the previous set of data. The object cache still has to de-serialize data if it’s serialized.

MySQL on a single server system does not use tcp/ip to communicate with bbPress if it’s properly configured (and most are unless your host is greedy and stupid and uses a central mysql server separate from your regular server). So MySQL with a properly configured cache is almost as fast on a single server setup than a persistent object cache (unless MySql is overloaded in the first place).

So in conclusion, if you are on a shared host, object caching is not a viable solution for you because you can’t get any of the persistant memory options installed anyway. If you are on a single server setup but not dealing with a large number of connections, the mysql cache is probably going to be near the performance of a persistent object cache, and the real memcache would never be used in the first place.

Memcache was meant for large, inefficient installs like WordPress.com

WP.com serves many thousands of people simultaneously from many different servers. It uses several dozen queries per page load. It absolutely cannot just rely on the mysql cache, even with dedicated mysql servers. The average wordpress/bbpress user does not face these problems typically.

If you have your own VPS or dedicated server you should be installing an opcode cache like Eaccelerator, APC or Xcache and turning on the shared memory pool option (typically during compile). Then you should make sure your mysql cache is ON and setup properly. Then you should make sure your pages are not using too many queries. If you’ve done all that and you have so many simultaneous visitors that your mysql is running too high a load and your pages are still too slow, then you can look at one of the persistent object cache modules for wordpress and port them to bbpress.

None of the bbPress installs in the Top 10, are using memcache or any kind of object cache for that matter (including wp.org which is using bbPress 0.9). So I sincerely question the need of anyone else using an object cache just yet unless they have made their install extremely inefficient somehow or have a horrible host.

[Ryan Hellyer]

Hmm, showing my total ignorance of caching here …

I assumed memcaching was the best way to improve the performance of bbPress and WordPress on a server even if it was only on a single server. So if I have a VPS, what specifications should I request to make sure it runs at maximum efficiency?

I”ve been contemplating moving to a 512 MB VPS and requesting they install mem cache on it for me. But juding by _ck_’s comments above that would be a stupid thing to do.

Any opinions?

[Sam Bauers]

@usera

You can setup a new memcached instance to avoid clashes with wordpress, but if you are sharing user tables then it shouldn’t matter.

If you add another memcached instance on a different port you can point bbPress to it by adding this to bb-config.php (default IP and port shown here)…

$memcached_servers = array( 'default' => array( '127.0.0.1:11211' ) );

[_ck_]

Memcache is only useful for multi-server installations otherwise it has too much overhead.

Eaccelerator, APC and Xcache have shared memory solutions that are significantly faster than memcache on a single server setup. But on a single server, it’s also been demonstrated a proper mysql cache can be faster than an object cache in some cases.

Eaccelerator, APC and Xcache can already store server session data in shared memory, you just have to compile with the option and turn it on in PHP.

There are plugins for wordpress that could be ported to bbPress 1.0 for the object cache but IMHO it’s a waste of time unless you have a very slow or overwhelmed mysql server.

[usera]

you are a lifesaver sambauers. I am using object cache but it’s not deeply integrated . The only other question is do you happen to know if you have to set a key (if you can set a key) to prevent object sharing. I know this is a problem with wordpress mu. I wish this was documented somewhere.

[usera]

I seem to have made a terrible booboo. I installed a clean wordpress mu 2.84a and than tried to install bbpress 1.0.2 with integration… I went to the last step and entered the same admin password for wordpress mu and I got Key Master could not be created! At this point it was completed but I went back to try to correct with a proper forum account and I get the “bbpress already installed ” message…

Anyone know a simple fix besides reinstalling bbpress?

[Sam Bauers]

“bbPress Live” plugin used to do this before WordPress 2.8 broke it. It’s on my todo list to fix it.

I want to create a button “Home” in header of bbpress to unite WordPress MU and bbpress. And vice-versa I want to create a button “Forums” in header of Buddy Press.

I’m not a programmer and I don’t know php-code very well.

How can I do these changes?
