OK, thanks. But now I have a new (but related) problem. I tried ftp-ing the whole WordPress directory to the new domain, but before it could complete the whole transfer, the ftp program timed out (a glitch it has sometimes) and the transfer got aborted partway through. No problem, I thought -- I'll just delete what was partly transferred, and start again, doing each file and sub-directory one at a time, so it doesn't time out. I deleted everything in the new location. HOWEVER, one of the files won't delete -- the ftp program gives an error message that says "550 Prohibited filename: .pureftpd-upload.47acd3e9.15.7cd2.c9e2f76b. Error 550." No matter what I do, it won't delete this file, or any of the directories it's nested in. How can I delete this file? And no, it won't let me change its name -- I get the same error if I try. Ugh.
