Hi, I updated to wordpress 5 and also updated all plugins. Somehow the color overlay disappeared. I used to have a blue color overlay at all my headers on: https://www.schilderaufsteller.de/  

I also noticed after the update that the menu has slipped over the header. You can't even read the first part of the text. 

thanks for support.

Don't mind! I found the problem. It was a caching problem.
