It works!
Now I remember reading about it somewhere..
Thanks a lot!
How did you fix it? I have exactly the same problem
These are the lines I added
<?php
if ( function_exists( 'add_theme_support' ) )
add_theme_support( 'post-thumbnails' );
?>
I’ve also tried to deactive the new plugins I’ve added lately and restart all plugins via ftp with no success
