Can't add to cart on mobile device

[reggaebkk]

Hi,
I checked 4 other posts on this topic and it couldn't help me.
I just realised that all works fine on PC but when on mobile devices my add to cart button doesn't work.
I checked modsec on server and it's not, I disabled my csf firewall, I disabled 1 by 1 all 3rd party extensions, I tested with other templates. I even installed jquery easy and tried about all possible configs... nothing.
Strangely I have virtuemart installed for the same client on another website will more or less the same configs and it works fine there.
It's just working fine on pc and not at all on mobile, it's not opening the confirmation popup, not adding to cart, just the small "waiting wheel" opens and nothing happens.
Any idea?

Maybe there is not much point continuing with this thread until you fix basic mobile friendly page issues.

Get a developer maybe to help you sort this and maybe they then can test for add to cart etc
