Bonk troubleshooting help

edited July 2014 in Vanilla 2.0 - 2.8

Hey guys. My vanilla forum has been running fine for ages and I just woke up to find it down with a bonk error. Here is the error message. Anybody know how I can fix this?

Fatal Error in Gdn_Database.Connection();

    AfaIk, that isn't a Vanilla error, as such, but a problem with your host and the mySQL db.

    Is it a transient error? Has it cleared now?

    nope its still there. hopefully it clears up later today. i'll ask my host in the mean time. thanks.

    EDIT: woops seems fine now. Talked to my host.

    "I have fixed the issue by pushing your domain to PHP5.3 by adding the PHP 5.3 handler type(AddType application/x-httpd-php53 .php) on your .htaccess file. You need to update your domain asap as it should be compatible with the PHP5.4. "
