Upon removing the Theme My Login plugin from my installation, this issue has been resolved. Unfortunately this plugin was an integral part of the site. If I can find a fix or a replacement, I will post back for anyone experiencing this issue.
Thak you Anrea_r
I am not returning a PHP error. I checked the log file and saw nothing out of the ordinary, then turned error reporting on and set to E_ALL to display on screen, and again received no error. I created my own page with a php error just to make that it was logging and displaying errors correctly and it returned the error as expected.
I originally installed 3.0.4 running PHP 5.1.6, found this issue, and upgraded to PHP 5.2.17 as required. I figured the old PHP version was causing the error (maybe requiring a php function not available in 5.1.6), but the upgrade to 5.2.17 produced the same result. I have since reinstalled 3.0.4 on the 5.2.17 and still the same result.
Can you think of anything else that may produce the white screen that would not return a php error?
Yes, I re-ran the forum installation with same result. I don’t see a problem with the forum setup, especially because it works when multisite is disabled.
When I manually upgraded to 3.0.4, I overwrote config and htaccess files with default values, I had to update these files with multisite settings to ‘re-enable’.
Actually, I had a Multisite install running WP 3.0. Everything working correctly. Upgraded to 3.0.4, re-enabled multisite, now i have a problem. If I turn off multisite the forum works just fine. Once I turn it on, I get white screen when submitting in forum.
Thank for the replies. I will try posting over in the WordPress forums. I did re-run the Permalink Settings with the same result.
Do I need to make any changes to my bb-config.php file to run multisite? It is not mentioned anywhere in the multisite documentation, but it seems that bb-press is involved on the pages that are failing.
