Problems : mobile menu, scroll top, header (works on HP)

Hi everyone,

I’m using this very nice template in a local area.
I’ve some problems in pages, not in the homepage.

First : the primary menu is not showing at the top on mobile when I try to reduce the screen.

You know it’s the three rods.

Second : The function of scroll top is not working

I click on it but nothing happen.

Third : The header of page is white (and the title too…) when I put a picture in the front.

If someone can help me, it would be very nice.

Thank you.

Julien
