I think I did something stupid... I must have forgot to deactivate my plugins before I tried upgrading my WordPress installation. My blog still works normally, but when I try to go to the admin page, or to the upgrade script, I get this:
Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, firstname.lastname@example.org and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. Apache/2.0.54 (Fedora) Server at unechance.com Port 80
And the address bar shows this: http://unechance.com/wp/wp-admin/upgrade.php?_wp_http_referer=%2Fwp%2Fwp-admin%2F
I searched these forums but can't find anything... Maybe I deleted the .htaccess file? Any help would be much appreciated.
