So the site has, as far as I know, been down for the better part of three days. WordPress is generating fatal errors which has been bringing the server to a crawl.
I have disabled some plugins on the site and I am hoping that this keeps the site running at least until I get home to investigate this further.
Sadly I am not within easy reach of a WiFi signal here (I am working at a Starbucks at the moment) so it will be until the 29th before I can sit down and give the site a good looking over.
My apologies for the inconvenience.
