FWIW – I have the same problem. I’m very new though, so don’t have much to add. It worked once for a plugin – but never again for anything else. I’m getting proficient with cyberduck and my cpanel though. . .
ack – now my site says that I am down for maintainance and I can’t log in! Breathe deep. . . so how do I get back into my site? Right now when I try to go there it simply says I’m down for scheduled maintainance.
