I am trying to get this to work with .zip files and a .sd3p file extension that I entered in and neither of them upload via the form field. They do work fine via the normal forum attachment option, just not in the form field upload. Am I doing something wrong? I have tried it with and without the periods.
The form field does upload properly a .png & .mp3 file that I tested. I would think .zip would definately be allowed.
