shopping application not loading after sandbox refresh

After a sandbox refresh I'm trying to get our sandbox Mont Blanc web store up and running. I cleared the cdn cache, deleted and re configured the domain and touchpoints, rebuilt the search index, rebuit the fieldsets and wiped out the mont blanc files and unzipped and configured the original code again but I'm still seeing the same problem. The shopping application does not load. I get a blank page for the index and the web store.

When I go to the log in, it works. I can log in and look at my account. If I just go to sandboxsite.com/checkout.ssp, I get a page not found error. I'm also seeing the "No 'Access-Control-Allow-Origin' header is present" error, but I have had that error before and all it affects are the fontawesome symbols in the header. It has never caused me a problem with the web store. Also, when clicking the search link, the search url is sandboxsite.com/?fragment=%2Fsearch.
