this happened to me on 8/16 (as the index page shows last edited) and I have just noticed it this morning.
i had both MT and WP on my server when i thought i wanted to do a blog, but never really did anything with it. i should have removed them both.
all my index pages are messed up. i have phpnuke running, and i don't have a copy of my website. i'm not sure what to do, as the support guys have over 500 unopened tickets to deal with (is everyone on vacation or what?). I deleted the WP folder, but the MT folder has some subfolder it won't let me delete so MT is not fully deleted yet.
i also had a gallery on my site, which seems to have all the images missing...sigh
any ideas of what i can do? can't dreamhost do a restore on my site or something? what did the rest of you do to fix this?
