I am running version 3 of wordpress (I can't remember the exact point release). I just clicked on auto update in the dashboard and I was presented with the "your site is down for maintainance" boilerplate. A few minutes later and I get this error:
Fatal error: Cannot redeclare class Walker_Page in /home/gkp99/garrypettet.com/wp-includes/post-template.php on line 1060
Now I can't view my site or even go to the dashboard! I'm completely locked out! How can I undo what's happened!!
