405 NOT ALLOWED .PHP FILE

Hi ALL

I encounter a problem on an application developped prestashop 1.6

When I try to connect via the application, I get: "16: 34: 19: 82 HTTP connection request result :: HTTP / 1.1 405 Not Allowed <\ r> <\ n> Server: nginx centminmod <\ r> <\ n> Date: Wed, 15 Jul 2015 2:34:20 p.m. GMT <\ r> <\ n> Content-Type: text / html; charset = utf-8 <\ r> <\ n> Content- length: 166 <\ r> <\ n> Connection: keep-alive <\ r> <\ n> <\ r> <\ n> "

Apparently, the application call a .php file in the directory modules

When I utlise URL to test POST ie (path : /modules/xx/xx.php) https://xx.php?email=xxxxx&password=xxxxx it does not execute the file, it asks to download: - /
path : /modules/xx/xx.php
I have enabled the management of https in the application.

I contacted the developer and he asked me to check the configuration nginx

Some ideas to contact me?

Thank you all
