A broken skin (named MonoBook2) was left in the skin directory and was user selectable. Upon a user selecting that skin, any future requests from that particular user account now receive the error: Fatal error: Cannot redeclare class SkinMonoBook in /var/www/wiki/skins/MonoBook.php on line 33 Utilizing "&useskin=monobook" will allow browsing the wiki while that account is logged in, and the skin section under Special:Preferences can be accessed, but attempting to switch the account to another skin results in the same fatal error upon attempted save.
Did you delete the file yet?
Welcome to PHP -- fatal errors cannot be caught.
