 * When trying to activate
 * Fatal error: Cannot redeclare class Controller in C:\xampp\htdocs\wordpress\wp-
   content\plugins\wp-pipes\includes\controller.php on line 11
 * Seems to be an incompatibility with Orilla Cart. Both tryies to declare same 
   class (Controller)

 * Dear **ogry**,
 * We are very sorry but it looks like you will have to choose one plugin to use
   in this case, since “Controller” is our main class and to change it would be 
   really hard work for us =”(
 * With best regards.
