I've enabled a session recorder in my production environment. I have noticed some users on occasion do not load the proper skin. The resulting skin is a disaster and the experience falls apart. Actually, I can't tell if its not loading the skin or just the css file. What could be causing this? Could they be getting a bad cache file?
I have not see any consistent pattern of device, browser or OS. But I saw one user who tried the site on 4 differenct browser/device combinations and all failed except for one page. After signing in, it went goofy again. On one occasion, it looked like they were signed in with access to the ACP!!! I'm concerned there is some caching issue.
A bit concerned and confused and looking for ideas.
