I know. I have tried that. And then the correct tab shows with correct information. But as you see from the developer of the theme above, they don´t know... And I told them that as you said.
I have deleted the whole theme and reinstalled aswell.
Perhaps I need to reinstall WooCommerce and even WordPress aswell?
But that feels heavy... And not sure I can get back all the products and the layout, when I dont trust the backup.
