First off, im panicing!
I was running version 2.1 of wordpress and decided, since I am bored at work, Ill do an upgrade. I followed the steps online, except didnt backup my current wordpress directory. I replaced all the filex that were on my server with the new wordpress files, except I didnt touch the themes in the wp-content folder. Now my blog has disappeared, there is no place to login, nothing. can someone please help!!!! Im freaking out!
