When in the admin screen and clicking on presentation I am getting the following:-
Fatal error: Call to a member function on a non-object in /files/home3/andre02/wordpress/wp-includes/functions.php on line 1491
Everything else inthe blog seems to work. (http://cgi.andre02.plus.com/wordpress/)
I have deleted and reloaded every file in wp-include with no sucess. There are no zero length files either. The rest of the admin pages work fine. I just cannot change themes.
