I have two different phpBB 3.x boards, running under two different users and using two different sql servers. One is highly modified, the other is literally the default Dreamhost one-click install.
The file attachment feature of both stopped working simultaneously sometime friday or early saturday. I cannot figure out for the life of me why this happened or how to solve it, or even what I could have done to have both of them stop working simultaneously across two FTP user accounts and two different sql databases.
Contacted Dreamhost but they've yet to get back to me, presumably because of the holiday.
Both of them are hosted on Adams.
