System Administrators can't see any VisualForce Pages.
Beginning this morning sometime all System Administrators do not see anything but the Salesforce menu banner. If we impersonate another user we can see the Visualforce/Skuid pages with no issues. But the moment we switch back to our own profiles nothing loads. Was there a change that occurred in the last 24 hours that would have caused that? I will report back if I find something on my end.
