Hello. On some of the networks I am running, when I enable the Remote login option, the sites load fine with the mapped domains, but in my browser console I'm getting a 403 error on the domain mapping script tag that gets included in <head>. (The one making a call to the primary site with the ?dm=xxx... query string.)
Any ideas why this would be? It's weird because I'm not getting the errors on one of the networks, but I am on the others.
