Struggling with this a bit and i wondered if anyone had any ideas. I upgraded my blog from wordpress 2.8.5 to wordpress 2.8.6, and now when I go to wp-admin, it's just throwing me out to the wp-admin/install.php screen... I've trying reuploading the files (just to make sure I didn't miss anything), removing plugins, disabling the .htaccess... Also made sure i hadn't over written the wp-config.php (which i handn't) still nothing. Any and all help gratfully received cause I'm kinda at a loss what to try next!
Edit: Also made sure i hadn't over written the wp-config.php (which i hadn't), and checked the Db is still there through phpMyAdmin (which it is).
