Hello, I did the quickstart installation, it worked normal. But when creating a new category and adding a new product in this category the view of it is not the same as the other products already registered.
I checked and saw that css changes as shown below:
Did you assign the sub-template correctly in your shop menu?
In your site backend after creating category and products go to "Menus -> Main menu"
Then open your shop menu and click the "Common options" tab and check that do you select the "Sub-template" as "bootstrap3".
Let me know if any issues.
