Hrmm…. Not sure I’ve run into this one before.
Are you trying to access it by going to the “Add-ons” page and clicking on “Structure”
Or through a custom nav item add on the left hand side? (Wondering if this might have an old session ID or something along those lines added into the navigation link)
Thanks,

I’ve seen this before. In most cases, you need to clear cookies and ensure you have a fresh session. You can verify that is the issue by trying in another browser / incognito.
