Personally, I’m considering downgrading, if such a thing is possible. >< This 2.5 is really giving me headaches; first it messed up my layout, and now I can’t even access my admin page-! I ended up having to overwrite my index.php to put up a splash page. Hahah…. God, and it’s finals week, too. I don’t know what I was thinking, opening a can of worms like this.
I’m having a similar problem, but I’m getting an error that says:
Fatal error: Call to undefined function has_action() in wp-admin/includes/plugin.php on line 403
It seems like our problems are similar.
