For the past two days when I try to upload a layout I get this message:

You don't have permission to access /photopost/bulkupload.php on this server.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

My image does end up in que though so I can go in after and fill in all the details and submit it fine. Just really annoying and if you don't know to how to go around it, it could affect those entering the Supreme Team Contest.
