Have you tried:
-
deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
-
switching to the Twenty Eleven theme to rule out any theme-specific problems.
-
resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
-
re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress.
Tip from a thread in WordPress forums.
