This morning I found out my website died overnight for no apparent reason: http://reginator.net.
When I try to log into http://reginator.net/wp-login.php to see what happened I get the following error: You appear to have already installed WordPress. To reinstall please clear your old database tables first.
I haven't made any changes or updates recently but the website is down and I can't log into WordPress admin. I'm using Thesis as the theme.
Any help is much appreciated!
