Hello,
1/ I do not see the problem – https://prnt.sc/plTEUwImVcj3
Try to disable “Menu Dropdown Ajax Loading” and “Menu Dropdown Cache” via Theme Options > Speed Optimization.
Clear all cache and check the menu.
2/ Activated – https://prnt.sc/sRmibytH6k12 > https://prnt.sc/xXse1MchvWJR https://prnt.sc/OqMqad3MT_-d > https://prnt.sc/39qK7Xb6omF0 Please check.
3/ Yes, it was changed. Do you want to change it to the old view?
4/ I’ve passed it to our dev team. What should we do to be able to see the error on the product page?
Regards
