 * 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 default theme to rule out any theme-specific problems.
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems.
 * – re-uploading all files & folders – **except** the wp-content folder and wp-
   config.php & root .htaccess files – from a **fresh** download of WordPress. Make
   sure that you delete the old copies of files & folder before uploading the new
   ones.
