Tonguc

to be honest, I tried every opportunity if I force JS into head, I have another Error: “Cannot read property ‘className’ of null” AND my toggleNav doesn’t function ??
That’s the reason why I exclude JS from optimization generally.

Thank you, superpoincare! Indeed it works with your code:

var $ = jQuery.noConflict();

the Problem was the toggleNavMain, which works with JS.
The Problem is solved, but unfortunately i have to exclude JS from optimization.

sorry Frank, but after “force JS in head” I have a new problem:

autoptimize_496e0af6a30c10b799916c6ca749b5ec.php:46 Uncaught TypeError: Cannot read property ‘className’ of null

Thank you Frank!
