Remove background grid (not product)

Hey guys,

thank you for your great extension.

I want to remove the background grid like you talked about here: https://support.fancyproductdesigner.com/support/discussions/topics/13000021495

But i do not use fpd in a product, I integrated fpd via shortcode on a wordpress page. Try it here: http://r.stainer-sunwood.com/dekordesigner/

A dirty workaround would be to use a white image as background, but maybe you have a better solution.
