I've had wordpress running for quite a while now (upgraded to 2.1 a week or so ago). I tried to activate a new theme tonight and I get this error:
Fatal error: Cannot instantiate non-existent class: custom_image_header in /-/blog/wp-includes/theme.php on line 576
I can't do anything in the admin area.
Also, the public index gave an error for a delicious plugin I was using (worked fine until now) -- I renamed the plugin directory until I can get the admin issue resolved and deactivate it to see what it's problem is. S
Suggestions, anyone? Thanks :)
