I have lately encountered quite a few problems with the problem I'm about to describe. I think it would be good for all of us to know the solutions if anytime we encounter this problem.
I know my content is larger than the screen and I have a vertical scrollbar. However, the problem is that the vertical scrollbar is not displayed well in the browser. In fact, I can only see the top part of the scrollbar and not the bottom and the scrollbar sort of looks disabled, therefore I cannot actually scroll my content neither can I click on the scrollbar. However, if I 'inspect element', I can actually see that all my content is being loaded into the page.
Anyone of you guys ever encountered this problem?
