I deleted the WP-DB-Backup plugin from my plugins directory this afternoon and instantly broke our site. Since then it's been returning either an Internal Server Error 500 or an Error Connecting to Database.
I tried dragging over a version of the WP-DB-Backup plugin folder from several weeks ago in my FTP client without any luck. It's not our MySQL database; another site using the same database is up and our Host confirms the problem is somewhere in the directory files.
I can't get to the Admin area of the site, obviously. Should I try uploading a clean install of the plugin? I hadn't even configured it yet so I won't lose any backups from there. Need advice desperately, we've been down for 5 hours now.
