I am using 2013 Enterprise. I have a single web app in a single zone. I have users in a Client AD forest and users in a Corporate AD Forest. There is a 2 way forest level trust between domains.
I added 3 lines of JavaScript (it hides some page elements) to the bottom of my masterpage (A copy of it). I checked it in and published a major version. I set it as the default master page. I did this in Designer.
I can see the changes have taken affect when I login with my user account. I can see the script on the page when I view the source. When I log in as a user in the Client AD forest the changes aren't seen.
Any ideas?? Any debugging tips?
