And it looks to me that zip is allowed
Ok, the system picks up the mime type of the file. It could be that Winrar and 7zip generate slightly different mime signatures. I'll look into adding some error reporting where the mime type is wrong so that it includes the mime type it received in the error. That way I can add the additional mime types that may be generated.

Please subscribe to this thread, and I'll post when I've made the changes to the upload routine. Then you can try again. Capture the error message and send it to me so I can add the missing mime types.
