On my site I have an email at the very top. It was in a custom module and wasn't being protected. I thought it would have been as email protector protects all modules/components even 3rd party, but that was my mistake. I turned on "prepare content" which seems to have solved the problem.
But now the content takes up 0 height. I change that in CSS but I still don't see the content and it doesn't take any of the colour values that I ask it to take.
