Hello... I get this fatal error when I click on the Presentation tab while logged in to wp-admin:
Fatal error: Call to a member function on a non-object in /home/content/l/u/x/luxout/html/wp-includes/functions.php on line 1489
I just installed WordPress 1.5.1 yesterday and everything was working fine. Then I logged on today and started getting that fatal error message when I click on the Presentation link to edit my themes.
I've looked at line 1489 of the function.php file and it is identical (unchanged) to the one I originally downloaded yesterday. I also reinstalled the entire WordPress 1.5.1 application and I still have the same problem. My URL is http://www.visceraldrives.com/
Any ideas are much appreciated, thank you!
