with widget logic you can call ‘is_bbpress’ that will determine if you are in a forum page

I am importing an arabic vbulletin 3.x forum into bbpress.I am facing character encoding.vbulletin db has latin1 charset so I converted all tables to latin1_swedish_ci.after importing topics gose weird with blank titles.Any body help

Lee!

[Clivesmith]

OK thanks, I have tried deactivating nearly all the plugins just left bbpress / style pack and it is still the same, also as I said chopped the functions file.

[Robin W]

It could be a theme or plugin issue

Themes

As a test switch to a default theme such as twentyfifteen, and see if this fixes.

Plugins

If that doesn’t work, also deactivate all but bbpress and see if this fixes. if it does, re-enable one at a time to see which is causing the error.

Then come back

[tedf]

here is an updated image of the problem … the red arrows identify the problem areas.
i am not sure if they are called headers, menus, or as one person suggested, “lists”.

the problem is that they headings and data items don’t line up.

if you google bbpress forums, and look at the images, all the pictures show the data properly lined up.

My request / idea for this topic comes from being involved in WordPress.com and WordPress.org forums. As people in these forum may know, there is a lot of confusion about where to input topics when people need help with WordPress. Because of this confusion, it leads to many Topics (basically support tickets) in the wrong forums.

An example of this is when people post to the WordPress.com forums for a question about a self-hosted WordPress site. This takes the staff and volunteers working on WordPress.com away from supporting that system and instead causes a need to support this other question and most of the support is educating the difference in .com and .org. Once those replies go the tickets, some people opening the topics are still not sure what to do – and telling them “go to the other forum” might be confusing, and at the least will cause duplicate work.

So, the idea: a feature in bbPress that allows a forum (in this example, the WordPress.org forum) staff to “pull” a topic from another forum (WordPress.com forum) and get the data setup as a topic in the forum where it makes sense.

Ideally, this would pull over the threaded history, somehow note the users in the discussion as users of the old forum or the new forum (maybe call user: username[wordpress.org] vs username), and tags as needed…and then allow the discussion to continue on the new forum while noting the move and closing the ticket on the old forum.

There is a problem that the user opening the topic needs to exist – and the user in WordPress.com may only exist in that system, so one option would be that part of pulling the topic over would do an automated user creation behind the scenes on the “new forum” if a simple search did not find the user to assign the topic to in the new forum.

I also think that in order to do some kind of migration of topic from the UI side (just past in a URL and basically “scrape” the data) would be nice but for the better administration the data would be pulled with API calls and this could be done by URL and some kind of nonce/code that only a staff members who has high access on both forums would know/generate. They log in to the old forum, go to the Topic they want to copy and click something to enable the copy – this would give them the nonce/code. They go to the new forum and note where they are pulling from URL, the nonce/code and the user they want to assign the topic to in the new forum.

This is a long winded explanation, but I think similar to other situations where a company or organization could have a legitimate need for multiple forums platforms (instead of just splitting by forum in one site) and a method to essentially “move a topic to the right forum” could have a nice benefit – not to mention the simplification of support for the WordPress community.

I would love feedback and if this is something useful, it would be great to know what the next steps are to follow through.

(this is a similar idea to what is in https://bbpress.org/forums/topic/copyduplicate-topic-into-another-forum/ but it seems different so I did not just put a reply there)

Hi,
There is currently no easy way to go deeper in the structure. A ticket is still open for that: https://bbpress.trac.wordpress.org/ticket/1958
Pascal.

[Jing]

We would like to add a section for helpdesk and user suggestions.

We would like to list this section as a separate component of our Forum section.

What shall we do to display the helpdesk section separate from the rest of the discussions using bbPress?

[tapiohuuhaa]

Get working with the plugin. I just changed one text, which was not in the report.php file.
Next time when I update the plugin I must add translation as code snippets.
Thank’s.
Yes, I don’t understand, what is child theme function.php file.
I have used twentyfourteen. I don’t have any child theme for it but the theme does have function.php.

BTW. A Finnish user had complained in the conversation page of the plugin moderation-tools-for-bbpress about the same issue (I saw from the nickname that the person was Finnish).

Hi,

how can i insert ads to bbpress forum? Is it possible only via advanced ads paid version?

Thanks

[misha96]

Hi,

I changed a theme and suddently saw that my bbpress forum changed its color (to red – check the link).

There is no option to change the text color in widgets, forum options or appereance…How can i change it to the black text as it used to be?

It has something to do with words that can be clicked on (so with url inside) – where to change it please?

Thanks!

[tapiohuuhaa]

I got all other front end texts translated into Finnish using *.po(t) files except text of moderation-tools-for-bbpress.

[tapiohuuhaa]

Sorry about my inappropriate words, but I just assumed that if some text is used for ordinary participants, the text should IMO be translate able.

If there is no translation using po/mo-files then fields to set the desired text like in bbp_style_pack. Indeed that doesn’t work with multilingual sites if there is not another installation or WordPress for other languages (I don’t have looked, how WordPress could work with multilingual sites).

I don’t figure which function file Robin W. means. Many plugins has the functions.php file.
moderation-tools-for-bbpress does not have functions.php (like for example bbp_style_pack or the used theme has).

[tapiohuuhaa]

How to get front-end texts translated in Finnish? moderation-tools-for-bbpress

does not have any *.po or *.pot files.
These should get translated:
* approved
* report
* report reason + all related options

WP : 5.0.2
bbPress : 2.5.14
Theme : Custom (built with _S)

Hi everyone,

I just noticed that in the forum freshness block, I get a “aucun nouveau sujet” (no new topic / messages) message when nobody post something in the forum in the last 7 days.
Do someone know where I can customize that ? I just want to have a classic message, for the last 7 days, a month, a year or whatever.
Cheers,

Chaaampy.

[N. Ahamad]

Ok. I tried the old one. And also just now tried the RC 2.6 . Somehow, the conversion still stuck at converting topic. I need some help.

When the topic conversion process, is it smf_message or smf_topics table?
As for bbpress, all of them convert as wp_post and set as post type =forum right?

When the conversion stuck no go at all (not hang). It’s hard for me to find which table or column is the culprit. When I sorted the post in smf_message by ID,I found the post. but seems the wp_post one not the same as it, even the some post are pass or newer than highest id in smf.. it confusing me.

Maybe i just dont get it how the conversion goes on…

This is really tiring.

[tedf]

I am trying to add a forum to my website, using bbpress, .

I ran into a problem with the forum layout in a “heading section”?

I don’t know what to call it, and can’t find a reference in the documentation, or via google.

It is the heading that holds … topic, voices, posts and freshness
Something is too wide, so they wrap ..
Both in the heading and In the content below

– see link

I removed the sidebar widgets, but that did not change anything.

The theme I am using is Rise.

i an looking for help to get it lined up so it doesn’t wrap?

thanks
wp version 5.0.3
bbpress 2.5.14

rise 1.401.1

[Robin W]

bbpress is compatible with 5.0.3 and works fine on my test site.

It may be a conflict with your theme or plugins

Themes

As a test switch to a default theme such as twentyfifteen, and see if this fixes.

If that doesn’t work, also deactivate all but bbpress and see if this fixes. if it does, re-enable one at a time to see which is causing the error.

The order should be (I think):

Users
Forums
Topics
Tags
Replies

Agreed, this is necessary for large imports, I initially had a database of 110K+ users and 2.2 million posts/topics, which after 13 days of importing I decided to prune before attempting again.

In theory, you could rearrange these yourself by altering the wp-content>plugins>bbpress>includes>admin>converter.php file and changing the order of the steps. I actually thing the tags are the least important step for my site & the one that caused the most headache/issues while importing, so I made that step the LAST step.

I was importing from my Vbulletin 4 and it went through converting topics, then it started converting tags and hung about 12,900. Is this a known bug? What’s the best way to do this over without losing the imported content and without taking risks of missing content not being imported initially on the hang up?

I’m a day late and a dollar short, but I thought I’d answer this for anyone else experiencing a similar issue.

vB4 tables originally used latin1_swedish_ci Collation, so when they’re imported certain characters don’t import properly causing the import to hang.

If the bbpress converter hangs up you can see what the last query was running. go to your WordPress MySQL Database:

Find the wp_options table (note that your table prefix may be different)

1. Shut off the importer (hit the STOP Button)
2. Go to the wp_options table & do a search for %converter% – it will return 3 tables

  a. _bbp_converter_query
  b. _bbp_converter_start
  c. _bbp_converter_step

Select both _bbp_converter_start AND _bbp_converter_query and click edit. Look to see where the tags got hung up in the option value field-

(here’s an example from my own database):

SELECT convert(tagcontent.contentid USING "utf8mb4") AS contentid,convert(tagcontent.tagid USING 
"utf8mb4") AS tagid,convert(tag.tagtext USING "utf8mb4") AS tagtext FROM tagcontent AS tagcontent INNER JOIN tag AS tag USING (tagid) LIMIT 2750, 50

In this case, it’s getting hung while imported tags 2750, 50 rows at a time.

change the values to the next bracket (but don’t alter any other data in the fields,:

_bbp_converter_start  2800
_bbp_converter_query 2800

and hit save

so now the option_value of the _bbp_converter_query looks like this:

SELECT convert(tagcontent.contentid USING "utf8mb4") AS contentid,convert(tagcontent.tagid USING 
"utf8mb4") AS tagid,convert(tag.tagtext USING "utf8mb4") AS tagtext FROM tagcontent AS tagcontent INNER JOIN tag AS tag USING (tagid) LIMIT 2800, 100

(note the new LIMIT number)

Then hit the START button on your Converter. IF, for some odd reason it doesn’t automatically restart, don’t freak out. Just hit the STOP button again, open a new page for the import

http://YOURDOMAINHERE.com/wp-admin/tools.php?page=bbp-converter

Re-enter your data, with the rows limit at 100, delay time the same as before & convert users STILL

Checked (if it was to begin with) DO NOT CHECK START OVER or PREVIOUS IMPORT.

Hit START and it will pick up where it left off.

Alternatively, you can
2. remove the offending tags from vbulletin –> /admincp/tag.php there are 45 per pg
3. update thread counters
4. Start the importer, see if it updates
5. If so- you’re all set *until next time* (and there WILL be a Next time!)

[budget101]

When it hangs it says something like: Importing Discussions (x-y) then all of a sudden it just prints “-” every 5 seconds or so and nothing is being imported,

Unfortunately this reply comes far too late to help the OP, but hopefully, this will help someone else down the road.

First, before you begin your transfer of vBulletin, add the following lines to the top of your wp-config.php just below <?php

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );

This will create a debug log of any errors you encounter, you can access the log by visiting
https://YOURDOMAINHERE.com/wp-content/debug.log

keep in mind that if your wp install is within another folder, you’ll have to alter the path in the url to access the log.

Next, once you’ve encountered an error, check your debug log, if the error isn’t listed, you can go to your MySQL tables.

Hit STOP on the Importer. (Don’t navigate from the page, just hit the stop button).
Go to the wp_options table (might be slightly different prefix depending on your own database settings) and do a search for %converter%

You will find 3 rows within the wp_options table

a. _bbp_converter_query
b. _bbp_converter_start
c. _bbp_converter_step

The Step will show you which step # your install is hung up on. The Converter query will tell you precisely which line and the start is what tells the bbp_converter where you last left off.

View the steps in your wp-content>plugins>bbpress>includes>admin>converter.php file

Step 1 (about line 339)
Step 2 about line 360, etc

Most often the issue is due to character collation.

Thank you for the fix, It’s appreciated.

Oops! I think that’s the original WP code itself. Anyway, I found another code to fix in bbPress. Pls let me know if I should post it.

This goes without saying, you should ALWAYS share a fix, you never know who’s going to be searching for it, sometimes YEARS after you find it.
