Mail setup Not working

[spd54]

Just did a clean  loaded of AbanteCart and when I try on go to mail under system so I can set up notifications i get the following:

Method Not Implemented

GET to /index.php not supported.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Anyone any idea what the problem is it worked in a previous version.  Website is hosted by Hostpapa

Had this before... configuration file had _default added... only needed a rename

Sorted.  Hostpapa Tech guys found that it was mod_security rule (1234123447) triggered, they disabled it and all working fine again.
