There aren't any required changes. There are things you can do, but none of them are strictly required and almost nothing is really a big deal going from 2.4, as that was the big cleanup IIRC.

So the best answer is, stop what you're doing and undo all of it so you're running an upgraded system with the same configuration and only make changes once it works again.

The logs will tell you anything you need to know about what it's getting and what it's doing with what it's getting.

Hundreds of reasons, I'm not going to just guess. You haven't even identified a platform. If you're using Apache, you shouldn't use headers to start with if you can avoid it.
