When using a modern browser such as Chrome 67 or Firefox 61, the OpenManage Switch Administrator Web UI on the N1100 series of switches fails to show the the main panel - only the header and left hand navigation are shown. This prevents the usage of the Web UI for viewing information or changing the configuration (i.e. it's useless!).
Opening the Developer Tools in Chrome, the reason the main panel fails to load is due to a Cross-Origin Frame Access Violation. One of the loaded scripts attempts to access the main panel frame but this fails due to the violation.
Due to this issue, It is only possible to use the Web UI via a less-secure browser that does not enforce Cross-Origin Frame protection such as IE11.
The switch(es) are running the latest publicly available version of code from Dell - 220.127.116.11.

Does the switch still have an older firmware revision on the backup image? If so, are you able to boot to the older firmware and see if the same behavior is seen?
I'm afraid I no longer have any switch with an older version in the backup partition, but from memory this also occurred previously - it's only now that i've finally gotten around reporting the issue.
Thanks Daniel, it should be quite easy for them to reproduce but i'm happy to try things and report back if they need more information.
