Mobile menu not working with disabled/unused news header

Like 2 other threads, same here.
The mobile menu button won’t work, test it with Google Chrome (iOS), Safari (iOS) and Chrome (Win) with mobile view.
I disabled the news header via CSS and don’t use it.

Hello there,

I am sorry to hear the issue you’re having. There might be some lines of script in one of your active plugins which stops the mobile menu from working. Please try to temporarily deactivate all of your active plugins. Whenever you get the mobile menu works properly, to narrow down the source of the problem, activate your plugins one by one.

Hi,

I disabled all plugins except page builder, and the error still occured.
I will let the plugins disabled so you can check it too.

I removed the example blog post and now its working fine
