I am working on a new deployment of ArcGIS Enterprise 10.7. As I was testing the new ArcGIS Portal Server and Site, I noted when you navigate to the Organization > Status page on the portal Home site an error message is received in IE and Chrome. All other pages appear to be working and I have not federated yet. The error indicates "This Content cannot be displayed in a frame". The error occurs weather you are accessing the site directly via port 7443 or through the web adapter. Screen shots below including browser console errors.
I noted both are reporting a frame error as well as a user not logged in error. I am logged in as the portal administrator and all other pages/tabs are working. I also tried to add a HTTP Response Header to IIS for X-Frame-Options on the Portal Web Adapter using both ALLOW-FROM and SAMEORIGIN. This did not help for either IE or Chrome.
I did find if I click the "Open content in new window" from IE, I am asked to sign in again from a new IE Tab and a 404 Error message - page not found will display. However, if I then go back to the original page and refresh the status page will load or anytime there after.
Any ideas? Will put a ticket in on Monday but thought I would try posing here in the mean time.
