Here's the error: Notice: Undefined property: IndexController::$express_start_time in /home2/kaxus/public_html/override/classes/controller/FrontController.php on line 185

 

I've also checked that add new products or edit products "save / save and stay" buttons are not working so I can't even upload new products and edit the current ones. Front office working perfectly fine though
