for anyone that was following my discussion with @NSN earlier, we figured out the "Page Not Found" issue. It looks like NetSuite now enforces valid domain extensions, which is a recent change. In my development account, my website was using a domain name that had a fake domain extension. I went through the effort of creating a new Domain | Website | SSP Application, and when I went to create the new Domain, NetSuite would not accept a domain name that has an invalid domain extension. This is relatively new, as I setup the original domain I was using back in March. Updating my existing Website & SSP Application to use a fake domain but with a valid domain extension (ie - foo .shopping), I was able to get my SCA site working again. We also received a response from NetSuite directly with instructions to update the Domain to use a valid domain extension. Hope this helps others.
