I guess it’s a problem with the install wizard. I was able to get cookie-based cross-platform login going by performing a clean install without running the integration during install.
1. Perform a clean, standalone install and log in with the provided admin login.
2. Go to Settings . WordPress Integration – Input the blog URL twice, enter the blog ‘secret’ from [blog_url]/wp-admin/options.php, and enter the blog prefix.
3. Update the blog wp-config.php with the two lines suggested by WordPress Integration Settings page, and you should be in business.
Hope this helps someone else out there.
Used WP 2.5 & 2.5.1 – bbPress 0.9.0.2
Well… apparently, the hangup is in using the “wizard” installation (which results in some silly “duplicate table” error regarding wp_users – users_nicename).
My fix was to perform a clean install, without checking the option for integration during the install ‘wizard.’ Once I was in with a standalone version, I went to the Forum admin page – wordpress integration settings. I input the WP URL twice, the secret from WP and the user table prefix. Added the two lines suggested for wp-config.php and bada-bing… that did it.
Hope this helps someone else out there.

Hah! I won’t quit so easily, even if it simple for users to log in twice… but, how annoying!
There is certainly something wrong with the cookie… but I’ve got the right wp cookie hash, and verified that bbpress picks it up naturally. I’ve got the secret keys with really simple text strings (for now), so I know they’re OK. I’ve verified the wp database secret is correct in the bbpress install. I’ve got COOKIE_DOMAIN defined as ‘.mysite.com’, and COOKIEPATH and SITECOOKIEPATH set as ‘/’ in my wp-config. I’ve got all 13 bb-> items listed in the 101 set correctly in my bb-config, with cookiedomain set to ‘.mysite.com’, and cookiepath and sitecookiepath set to ‘/’. My blog is in the web root folder (mysite.com) and the forum is in a subfolder (mysite.com/forums). My blog was established before bbpress was installed.
This must be something simple, and I’m just so frustrated that I’m missing it. Do I have to do something different with the cookie path – i.e. define it as the subfolder or something??
Thanks for any help!
This seems to be a problem with the install files. I have tried four different installations now, and integration causes the error with “user_nicename” in the wp_user table regardless of the correctness of all the other information (secret key, et al).
First run will produce the user_nicename error as well as the ‘Forum could not be created’ error. Second run will still produce the user_nicename error, but not ‘Forum could not be created’ – after the second run, the forum is installed and accessible… but cross-platform (wp -> bbp -> wp) cookie-based login is broken. Logging into the forum kicks the user off of the blog and vice versa.
I’m beating my head against a wall with this one. Anyone have any ideas?
Thanks for any help you can offer.
Hello! I am having the same problem. I have successfully integrated my blog (wp2.5) with bbpress (0.9.0.2) using a single database and I even tweaked the theme to match my blog (woo-hoo!). However, even after following all the steps listed in the Integration-101 post (which was very helpful for integration, btw), I am having problems with cross-platform cookie-based login.
I can log in to my blog, yet I’ll navigate to the forum and not be logged in. I can then log into the forum, yet navigate to the blog and I’ll be logged out back there. They’re obviously connected, since logging into one affects the other… and the user data is pulled from a single database.
The bbpress settings all looked right from the admin panel and successfully found the information from installation so I tried manually setting the options (as described in the 101) in wp-config and bb-config – both ways, I get the same result. Logging into one kicks me out of the other.
Any ideas? I’ve been plunking around for hours with this, and it seems like it should be something very simple. You can see the live site here: http://onehigherpower.com
TIA for any help you can provide!
