Files not redirecting with Domain Mapping?

Quick question...

Domain mapping seems to be working great for the site, but all files are gone as if they are missing.

It seems to be a simple redirect that is missing or incorrect somehow, but I don't see where. htaccess seems to be correct. is now http://domain.tld

Any ideas?
