Hi, guys,

I´m getting this PHP Warning in my logs folder:

Code:
[05-May-2020 21:27:50 UTC] Request URI: /admin/orders.php?search=xxx&page=1&oID=9695&action=update_order, IP address: xxx

tried a solution from the post nr. 50, but didn´t work out here. Do you have any suggestion, please, what could I try?

Thanks
