I am getting the following error when trying to upload a file:
403 Forbidden

Forbidden

You don't have permission to access /beta2/ScriptLibrary/dmxEditor/dialogs/upload.php
on this server.
Additionally, a 404 Not Found
error was encountered while trying to use an ErrorDocument to handle the request.

Apache Server at www.___________.com Port 80

This happens with both File Manager and Gallery Add on. This page has a Pure PHP 3 Upload behaviour on it which works fine. It uploads to the same folder.

Permissions on the script folder are default and the upload.php file is present. The page with the HTML Editor on it is in a folder protected with a .htaccess file. Is this creating an issue as it does with Advanced Multi Uploader?

I can delete a file using the File Manager within this same HTML Editor box.
If I can delete, I can upload so the problem is not actually permissions at all.
What can be causing this?
