I try to upload a file to ANYWHERE in my website, and this just happened today mind you, and I am unable to. I've tried two hard reinstalls (all files removed) and it is unsuccessful. However, when I login to cPanel to do it the files upload just fine.
The files are not in use, they are ~2kb big, and I have more than enough space on my server to fit them.
Since I don't have access to a log right now I'll just post what happens.
It goes to "XFer" five times, and then gives up and changes the file status to "Upload Failed". Any reason why?
