I'm making a shop that you need an item to go to the link's page to get to the shop.

buy item>Get link>Use item>go to page with shop link> Go to shop (in that order.)

When i try to directly access the shop, it tosses this error.

Catchable fatal error: Argument 2 passed to AppController::setField() must implement interface Resource\Native\Objective, boolean given, called in /home/nirainia/public_html/adopts/shop.php on line 33 and defined in /home/nirainia/public_html/adopts/classes/class_appcontroller.php on line 169
