By now I have pretty much all functionality that I desired on our website, working. Except one little thing: when an authenticated user tries to access a page for which he or she does not have authorization, then this yellow 'not authorized' page appears. All other error pages are in our website's styles and colors, except that one. For some reason I cannot figure out how I can customize that page. I would like to style it like the login page, but with a red 'not authorized' text.
How can I customize that page?
