I have a Team site where whenever I attempt to save the “Navigation”, “Navigation Elements”, or “Page Layout and Site Templates” Site Settings, I am directed to an “Access Denied” page. I’m a Site Collections Admin for the site, but at some point seem to have locked down my site settings.
Any known causes/ solutions for this issue?
Edit: I’m able to consistently reproduce the issue on a new site collection using the steps outlined here, and the issue appears to be part of enabling the Publishing Features. I have not enabled/disabled any other site or collection features.
