I am afraid that nothing works fine…
The problem with menu 3rd tier already saw by yourself.
Let’s talk about the other:
Categories-Tabs working ONLY if I use the widget once. In the case of 2nd instance showing the same pictures on any click on any of the instances. The categories are not the same.
Product-Area, Categories-Tabs, and Category-with-product are cutting the down area of the products, they haven’t the right hight.
I will send you login details to another test site where you can see what I’m trying to say.
Honestly, after many years in the job, I have never seen another theme as buggy as yours!
I’m totally disappointed!
