Which version of Laravel are you using? Also, exact trace text of error 500 would help

I'm using laravel 4.2, and here is the error log :

::1 - - [28/Nov/2014:15:32:44 +0100] "GET /mia/laravel/public/patientList HTTP/1.1" 500 4391 "http://localhost/mia/laravel/public/users" "Mozilla/5.0 (Windows NT 6.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.71 Safari/537.36"

Use this as URL in browser

http://localhost/mia/laravel/public/patientList

What is the error text on screen?

it fucking works when I use the url !

So my problem is somewhere else..

I know I have an url problem because my application start with :

http://localhost/mia/laravel/public/users

• it's an authentication form, with a login and password label routed like: Route::get('users', array('as'=>'users', 'uses'=>'WUsersController@getIndex'));

then, I go to

http://localhost/mia/laravel/public/users/auth

• using post data submission, with this route : Route::post('user/auth', array('uses'=>'WUsersController@postAuth'));
• in this method I make sure, asking my database, the user has correct login and password, then I redirect the user to the patient list like this : return Redirect::route('patientList')->with('title', 'Patient List');
• but my url stay as '[...]/users/post'

the patient list route looks like : Route::get('patientList', array('as'=>'patientList', uses'=>'PatientsController@getIndex'));
