Hopefully I've managed to solve the original problem. If not, I'll make sure to post updates here.
I just got a message from the hosting service that there were problems caused on my server due to unusual activity on CDS.
Our host deactivated the site temporarily to allow me time to investigate, instead of doing anything more permanent, and I'd rather take this time to figure out what's gone wrong, instead of immediately reactivating the site and taking the chance that it won't happen again, and then perhaps having to deal with more sever consequences.
Please help me out by letting other members know what's going on, or directing them here for further updates as they become available.
I'll try to get this done as soon as possible, and to keep you all informed of any developments.
I thank you in advance for your patience while I try to sort this out,
-Your Friendly Neighborhood Admin, unfilthy.
