Trouble Logging Out

  • I’ve just installed bbPress for the first time at, and it looks like it’ll be a fun program to use. However, I received this strange error message when trying to log out:

    bbPress database error: [Table ‘rudycar4_bb.bb_online’ doesn’t exist]

    SELECT * FROM bb_online WHERE user_id = 1 LIMIT 1

    Warning: Cannot modify header information – headers already sent by (output started at /home/rudycar4/public_html/bbpress/bb-includes/db-mysqli.php:158) in /home/rudycar4/public_html/bbpress/bb-includes/pluggable.php on line 168

    How do I fix that?!

    That “cannot modify header information” error comes from having whitespace at the beginning or end of a php file, before the opening <?php or after the closing ?>. Check any files you edited and check any plugins for blank lines at the end of the file. If there is no problem there, maybe there’s a problem with the latest release. I haven’t checked it out yet to see.

    But, it’s from extra whitespace somewhere, looks like the bb_online plugin?

    What version of bbPress?

    Thanks kindly for the reply, Chris. It worked. I deactivated all the plugins, so I will test them one by one. I really appreciate that!

    Sam, it was the brand new version.

    Sam, I do have a question for you, however. How does one install Akismet to bbPress? I’ve had no luck.



    To get Akismet working, you need an Akismet key. You need to register at – you can check the radio button that says “Just a username, please.” and once you have an account, your Akismet key is in their somewhere (been a while since I had to look for it – but I think it’s “My Account > Edit Profile” and they “” key is there.) Once you have the key, you put it in your config.php like this:

    $bb->akismet_key = ''; // Example: '0123456789ab

    Just put your key in between those quotes, and you’re done.


    Did everything, but when I tried to activate it, I received this:

    Plugin could not be activated; it produced a Fatal Error.

    Is it that Akismet needs to have something special done to it?



    Did you activate the akismet plugin in the admin panel? If that’s where the error is coming from, I don’t know what to say. Maybe it’s a problem with the new release.
