Why i get a 500 (Internal Server Error) when i'm trying to get Modules list in Extensions? : After developing my website in my local server, i upload it to the web host. When i try to display Modules list in Extensions I get this error (form the web host logs) :
GET http://bamatco.com/dental/prod/admin/index.php?route=extension/extension/module&user_token=XXXXXXXXX 500 (Internal Server Error) (jquery-2.1.1.min.js:4) 
I used the 3.0.2.0 opencart version. 
Everything is ok on the local server. I tried to disable all the extensions, i uninstall a modifications that i had already installed (Frensh language pack), i disabled all the Events (in Extensions submenu), always nothing. it’s very urgent. Thanks.
