Whenever I or a member logs in, we first get a blank page with “site.com/wp-login.php” for the url. If I then close the window and go to my site we are logged in. Why is that happening?

According to godaddy— Looks like it’s connecting to MySQL just fine, but when it verifies my credentials and logs me into wordpress it just shows a white page. This shows the script is working, but the communication is broken somewhere.

Thank you.

Try disabling all plugins (including BuddyPress), and see if that fixes the issue. If it does, enable one at a time to find the culprit.

[Meryl]

Thanks Steve for your reply. I tried that before I posted the question. Any other ideas?

[Steve]

Try wp_debug in the wp-config.php file:
http://codex.wordpress.org/Editing_wp-config.php#Debug

WARNING: all errors will show on the site. Copy them all off the screen, and then remove wp_debug.

Pay special attention to the last few errors.

Thank again Steve for your help. I did as you said and these are the last two messages. I can’t make out what the problem is:

Notice: Undefined index: redirect_to in /home/content/m/e/r/meryl/html/csasprouts/wp-content/plugins/buddypress/bp-core/bp-core-filters.php on line 141

Warning: Cannot modify header information – headers already sent by (output started at /home/content/m/e/r/meryl/html/csasprouts/wp-content/plugins/buddypress/bp-core.php:565) in /home/content/m/e/r/meryl/html/csasprouts/wp-includes/pluggable.php on line 934

Maybe this can be a clue. After I put my information in the buddypress login area and click on Log In this is the url that appears with the blank page—http://csasprouts.org/wp-login.php

“Cannot modify header information – headers already sent” means there is extra whitespace in the bp-core-filters.php file on line 141. That shouldn’t be there unless you modified the core BuddyPress files.

The odd thing is that file/line number should be a comment (at least in BP 1.2.8) You can try to fix it yourself or:

-deactivate all plugins
-delete your current BuddyPress plugin
-reinstall BuddyPress

[Meryl]

I deleted the buddypress plugin by trashing it from my ftp server. I then reinstalled in through my dashboard and I’m still have the same error.

I cleared my browser cache. Should I have done anything else to make sure the reinstall was clean?

[Steve]

are you still getting the ““Cannot modify header information – headers already sent” error?

[Meryl]

Yes.

I just got this message
