Hello,

I have bbpress and wordpress installed together and they were playing nicely. I change the domain info in the config files and the WP admin to the domain name from IP as the DNS switch went through and suddenly (I say “suddenly” but I’m sure I screwed something up), I get the following errors when I try to login to WP:

Warning: Cannot modify header information – headers already sent by (output started at /home/payingfo/public_html/Wordpress/wp-config.php:22) in /home/payingfo/public_html/Wordpress/wp-login.php on line 12

Warning: Cannot modify header information – headers already sent by (output started at /home/payingfo/public_html/Wordpress/wp-config.php:22) in /home/payingfo/public_html/Wordpress/wp-includes/pluggable.php on line 275

I also get this error when I try to pull up BBPress:

Fatal error: Call to undefined function: load_default_textdomain() in /home/payingfo/public_html/wordpress/discussion/bb-settings.php on line 143

I checked for white space. Anyone have any suggestions before I scrap this and start on another install? I’ve built out quite a few posts and pages and am not looking forward to deleting the db.

Thanks.

Sarah

No reason to delete the db! You can always use something like PHPmyAdmin to change entries. The relevant settings should be in wp_options.

This was directly after you were in WP Admin > Options > General and changed only WordPress Address and Blog Address? You’d need to change back the options named “siteurl” and “home” respectively. Change them back to IP and see if the problem disappears.

Those “Warning: Cannot modify header information – headers already sent by ” errors are almost always caused by whitespace at the end of a file, most likely a config. Is there a blank line after the closing ?> in one of your config files?

I freaked-out last night and did a reinstall and closely followed all instructions on this site and http://www.devlounge.net/articles/the-ultimate-bbpress-guide/. I believe most of my frustration has been caused by an ever-shifting hosting environment during this project. The domain has now resolved and everything is working nicely again (after re-install).

About those header errors: I did find whitespace at the end of wp_config.php. Those few invisible spaces kill me every time.

Now, on to outstanding misc. CSS issues…

Thanks for the help.

I had the same problem. I had fixed it by ‘triming'(using trim function in php) value of ‘siteurl’ option in database and inserting it away.
