Weird problems since 10/18

not sure what happened, but one of my sites no longer functions correctly. alot of things such as the mysql doesnt work, settings no longer save, some files there were chmod 777 no longer were, and mainly i have cutenews installed, and when you clicked on the comments link, a window used to pop up with a form, now it just pops up the same page in a new window!

also, i had emails automatically sent to email me from a forum, the email was “info[at]” and now all the emails come from “”.

can someone tell me if dreamhost rebooted or has some errors or something? thanks.
