title: Laravel route doesn't get to the controller
body: <p>My project was working just fine till few hours ago. Some routes still working and some stopped. I tried to delete the new modification I made but the problem persists!!!!!
  For example, this route used to go to index() method at the guest controller and returns a gust view of activities, and still working fine:</p>
  
  <pre><code>Route::get('activities', 'guestController@showguestactivities');
  </code></pre>
  
  <p>and this line of code used to go to index() method at the activities controller, but for now it returns just whit-blank page:</p>
  
  <pre><code>Route::resource('admin/activities', 'activitiesController');
  </code></pre>
  
  <p>I tried to return just a string like that:</p>
  
  <pre><code>Route::get('admin/activities', function(){return 'Just string for Activiteis';});
  </code></pre>
  
  <p>but it returns the white page again.
  I found that there is a conflict happening with this resource:</p>
  
  <pre><code>Route::resource('admin', 'adminController');
  </code></pre>
  
  <p>once I remove it, every thing else works. But I need this resource and I can't just delete it.   </p>
  
  <p>Any help will be appreciated.</p>
