Using DNN 7.2.2
The tabs on Site Settings do not collapse, they are presented as one page.
Click the black arrow to collapse I get this error in IE 11:
You do not have permission to access this document.
In Firefox no error is presented, the page does nothing.
If I click a tab (Basic Settings, Advanced Settings, User Account Settings, Style Sheet Editor), the page refreshes to the proper section of the page.
No errors are recorded in the Event Viewer
Tabs in page settings, module settings and host settings work okay, the problem is only on the Site Settings page.
There are no other modules on the Site Settings page and the error occurs regardless of the skin.
What else could this be?
