I've been using CoreFTP successfully to upload WordPress theme files I'm working on, but now I've run into a problem.
Uploads were working fine for a while, then I left my computer and came back to it later. Tried to upload a new version of a file I already had on the server and it wouldn't work. It automatically retried 5 times, each time uploading zero bytes, and then said failed. No other error messages or explanations why.
To make things even worse, it deleted the old version of the file, and since it won't upload the new version now the site is all messed up because it doesn't have a CSS file that it desperately needs.
I've tried other files as well, and uploading to different directories, and all of my uploads don't work. I've tried shutting down CoreFTP, reopening, and reconnecting, and still no luck.
Please help! My site's broken now and I need to get uploads working to fix it!
