cPanel webdisk (webdav) won't connect
 

I have tried to link omnipresence with a webdav disk I have created via cPanel's webdisk option (webdav implementation).

Unfortunately and no matter what I do, I always get the following error msg:

'[B]WebDAV server failed conformance test.

Move without overwrite should fail when moving a directory to a location that is already in use.[/B]'

Please note that I can access and use the webdav disk via Finder and a number of other iOS and Mac tools without an issue (I can provide you with a list if required).
The only service I have an issue with is OmniPresence.

Can you please support me ?
I believe cPanel is a common tool for managing webhosting so making it work will benefit many users.

Thank You
