Long story short. I upgraded to 3.1 and had problems with no visual bar and had problems with Articles page not appearing. The first was solved by a short editing of the wp-config adding in the concatenate tables, which seemed to somehow fix it even after removing it from the wp-config, and the second was fixed by removing a plugin that did sitemapping, oddly.
Yesterday it was fine, everything worked. Today.. i can't access the wordpress admin page. After inputting my nick and password at wp-login.php, i get a fully blank page.
What i tried:
- setting index.php as the 'default'/root/wva
- disabling theme (lead to the main site going blank, twentyten did not appear)
- disabling all plugins by renaming the folder and making a new empty plugins folder
- checked htaccess to be correct
- replaced wp-login with a new file from the install to make sure it's not corrupted
- tried the 64/96/160 mb php/sql memory size fix
- visually checked the wp-config with the sample and it's fine
- checked for spaces after ?> in both functions.php and wp-config.php
All of these failed to solve my problem. This is the blog that i'm maintaining for work, so i would like to have it operational 'yesterday'.
