Mobile Nav does not respond to touches

[BBWeb]

Hey,

I've just started customising a PrestaShop installation and when testing on some mobile devices, I noticed that if the width of the page is <576px, the top nav stops working altogether.

I have hardly any modules installed (PS Facebook and a few others), and I've mostly only made cosmetic changes to the store as yet. I can't figure out what's causing this to break. I've noticed there's a media query for 576, which I thought was related.

It could be JavaScript, but I haven't touched those files.

PS Version is 1.7.7.1
PHP Ver is 7.3

Thank you in advance!

 

I have noticed that if you click/tap where the black mark is in the screenshot it works, but I'm unsure where/what this element is being moved.

Hey,

I figured it out -- I had a clearfix element above the menu bar! I'm a fool!
