This is something that has happened to a site I'm maintaining. I can't create product displays for many of my products because the select list of products in the product field isn't populated with many of my products.
I have a content type called "Product Display" with product field of type product reference. When adding products the select list of products is only display 10 of about 100 products.
Uncaught TypeError: cannot read property 'behaviors' of undefind in jquery-noconflict.slicknav
Failed to load resource: Server responded with a status of 403 (forbidden)
This leads me to thing it's a jquery issue, but not sure how to debug this further.
So, how do I get that list of products to contain all of the products in the store?
