loadind by default PHP

Hi everybody,

I'm really "new" on PLESK and i would like know hot to configure my webstite on PLESK 12 in oarder to load by default .php extension.

Ie : When i load http://mywebsite.com/page.php that works ! But when i load http://mywebsite.com/page : an error 404 is displayed! I need configure something in order to accept load page without .php extension

How to do that please ?

Regards
