Hi Mohammad!
I tried your custom css code suggestion but this simply changes the color of the current state menu item. The problem I have is that not every menu item is realizing the current state and therefor is not changing color at all.
The current state does not appear under the menu items ‘LEISTUNGEN, TV, INDUSTRIE, REFERENZEN and DREHORTE’. When I inspect the code, the ‘current_page_item’ code is missing.
I have already tried to recreate a new menu but the problem is the same. Can it be, its a JS issue?
Thank you for your time.
Hans
