Error: Uncaught DOMException: Failed to set the 'domain' property on 'Document'

If you go to this website: [login to view URL] And try to add 1 fish to cart. You will see the fish doesn't add, BUT then reload page, and you will see the fish in your cart. Error that is happening is: Uncaught DOMException: Failed to set the 'domain' property on 'Document': '[login to view URL]' is not a suffix of '[login to view URL]'. at [login to view URL]:1237:49 This domain [login to view URL] is mapped to a multisite remysreef.exoticreefimports.com. So the problem is in my [login to view URL] file. The script is hard coded to my main site incorrectly. <script type="text/javascript"> [login to view URL] = '[login to view URL]'; [login to view URL] = function() { fetchCart(); } I need to replace code for [login to view URL] so that when I set [login to view URL] to be primary it doesn't produce the Uncaught error when trying to add a product to the cart.
