Reply To: Icon menu

Hello,

If you want to use your custom icon or image for that category menu list. You need to go to Products >> Categories >> Edit specific category and upload image or icon for “Icon to display in the main menu (or any other menu through the site)”.

Your admin area is not accessible due to protection. It seems you install some plugins for website security. Just follow the screenshot which I shared above. This will surely fix the issue.

Best Regards.
