We have a customer's site that has lots of editors. Most are added to the "Administrators" group. I keep getting word from various editors that periodically the whole edit bar at the top of the page just disappears. They can be editing pages fine, but then when they click to one page, sometimes, the bar is gone. Sometimes they can come back later and it's there. Sometimes not. I also had one say if she clicked back to a previous page, then went to the sitemap tool and navigated to the page she was trying to edit, then she could see the edit bar.

I, of course, cannot replicate this. I login with their accounts, and cannot get it to happen. This is the only site it happens on (we have 20+ C5.7 sites.) The only difference between this one and others is this one has Advanced Permissions turned on (I actually don't know how it turned on, I suspect the client did it at some point.) But we were stuck with it at that point.

Please give me some ideas even how to hunt down the issue.
