Yes, it is dispatcher cache issue but it comes up often.
There is a page new-and-envents.html that is what we are trying to access.
Regarding URL - we have - /content/interflex/en/news-and-events.html page created and we are trying to access this page from our website - News and Events
This seems to load fine now. But it doesn't stay that way. It goes blank and it is because it appends "/" at the end when you try to access this page url.
