Hi,
I am using the Gk_bikestore template and I'm trying to add different variants of the same item. For e.g I have an item Dagger Mamba 8.6 which is available in two colours: red/green. I'd imagine to do that I would have to click on "Add Product Attributes/Options" in the article page. When I do that I get an error saying 500 Layout default not found. How do I fix this. Please help.
Have attached screenshots of what's going on.
Cheers,
Manik
