I have done this but I'm still not getting the right result.
I have deleted those 2 lines from Shop.php
If I then select the Personnalize layout option from the product page menu I get the graphic tablet with all the right formatting, the background image and everything in the right place. This is what I want for all products.
If I select the same product (Graphics tablet) from the category menu on the left then some of the alignment of the add cart button and qty buttons goes wrong.
If I create a new product it does not have the background image, the product border, the tab formatting etc.
If I copy the graphic tablet product to create a new product then I lose the background images, the alignment goes wrong and the tab formatting disappears. It reverts back to the original buttons for add to cart etc.
I assume selecting the product from the main menu calls a different class, but where is this set?
