I was notified of a little glitch causing some pages to show the admin view and excess two-factor prompts. This appears to have been a server caching issue. This would not have exposed any data or granted any special access, it was just a static cache of content being shown instead of sending it to the server code to save time.

The caching was only supposed to impact image files, but it looks like it somehow grabbed some page files too.

As server performance is now much better than it was when I implemented caching, and the performance difference is now negligble, I have opted to turn off caching for the time being.

If you experienced this problem, it should go away with just a refresh of the page.
