I auto-upgraded to 3.0 and now I cannot access my blog at all. I get this message:
Fatal error: Call to a member function add_rewrite_tag() on a non-object in /home/content/27/5251927/html/wow101/wp-includes/taxonomy.php on line 289
I contacted my host which is GoDaddy but they do not know what to do. HELP! PLEASE!
