I've been trying to upload to this site for a week now, but to no avail. The browser just loads for a while and then nothing happens. I've tried several browers, too (Opera, Mozilla, IE).

Uploading a small file just to try, I got "Error: Move failed to: 9704"

Help?

If it loads for a while and then nothing happens, it generally means that the file size is too large. What's the size of the file you're trying to upload?

I'm also getting errors uploading smaller files, which is a problem that will require investigating. I know there have been some backend changes recently, and it's possible that someone removed something necessary for the upload process while cleaning up the server. I went ahead and reported the issue in the official bug report thread.

I see. Thanks for the info.

Found the issue and (hopefully completely) resolved it. If your filesize is not exceeding the limit, you should be able to upload now. If problems still occur, please report back.

What exactly is the maximum filesize?

As of now, 20MB.

Oh, I see. That is far too little for my map with all the voice acting

Hmm. If I may ask, what filesize are we talking about?

90 mb without the custom music

Still getting this error on a ~110kb upload.

The URL you are redirected to causing to display the error?
I seem to not get this error, so this might be a permission problem on the frontend but these sort of should not lead to this error. Then again, I did not do too much here lately

It does that and does not upload the file. Permissions would be a good place to start.
