My site, Entertainium.org, has crashed after I installed WordPress 3.0. I did the automatic install and now I recieve this message, and only this message:
Fatal error: Call to a member function add_rewrite_tag() on a non-object in /home/content/d/o/u/douglasbuffone/html/wp-includes/taxonomy.php on line 289
I don't know what to do and I am very worried that all of my content has been lost...
Please help me. Thanks in advance!
