Ok. I'm not terribly familiar with server issues, but it looks like a server configuration issue to me. It doesn't appear to be a PHP error, but rather a server error (apache, nginx, etc.). The submit button does involve obtaining a file on another server (Steam's), and obtaining the contents for use by the script. I don't think any of the core User CP functions do that, so that may well be the issue. Perhaps an .htaccess setting is interfering? I'm just shooting in the dark though, since I can't reproduce the issue and the error is beyond my expertise.
