finkunlimited Posted February 6, 2016 Share Posted February 6, 2016 (edited) Hi Guys, My website has begun displaying "Notice: Undefined index: id_product in /classes/Product.php on line 2438" but I don't know what it means or how to fix it. Can someone help me please? Thanks, Justin Edited February 6, 2016 by finkunlimited (see edit history) Link to comment Share on other sites More sharing options...

elbuho30 Posted March 30, 2018 Share Posted March 30, 2018 I solved the problem by changing this in the defines.inc.php file: PS_MODE_DEV from true to false / * Debug only * / if (! defined ('_ PS_MODE_DEV_')) { define ('_ PS_MODE_DEV_', false); } Link to comment Share on other sites More sharing options...
