I recently updated to 2.8.4 and there were no problems. Today, after a couple of weeks of posting and managing my website as usual, I only get a blank page when accessing my control panel's entry page at wp-admin. The site is still running as it was before.
I can access the control panel if I click on the "edit" link in any post and, once there, only the entry page, the "appearance" page, the "links" page, the "pages" page and the "plugins" page are blank. I can access every other function, including sub-sections of pages mentioned above.
I can also post and edit.
After searching around in the forum, I found this entry:
http://wordpress.org/support/topic/278630?replies=8
and tried all the solutions in the link given there by a moderator. Nothing worked.
I did not delete .htaccess and regenerate permalinks, like another moderator suggested, because I don't know what I would be doing.
Can someone please help?
