Ran into the "Failed to move uploaded file to..." problem on GoDaddy. After pulling my hair out trying to turn on Joomla! FTP (is it possible on GoDaddy, I can't find anyone who's pulled it off), I noticed the 2M limit warning at the bottom of the screen. The CBSubs Core Plugin zipfile was of course bigger than 2M. A quick update to php5.ini and I was on my way. I'd suggest Section 8.3 of the CB Subs Manual point out this out, as GoDaddy's pretty popular and their default seems to be 2M.

I hope this message gets posted somewhere, I tried to respond to an appropriate topic but I needed to be a member to respond. I don't want to pay $75 to help everyone out.
