Add to Cart Button Not Working

[kenhood]

To the prestashop community. 

I just upgraded my prestashop with the 1 click upgrade from 1.6.1.8 to prestashop 1.7.4.4. My add to cart button is no longer working but keeping rotating does any know of a solution to get this fixed.

I suppose this happens in the Classic theme because your old theme would not work after upgrade, hopefully you didn't try to enable it.

If in Classic theme, look into the browser developer tools ->console and see what JS errors there are.

Hi.

I have same problem. When I try to add a product in cart that sometimes dont work. I tryed in opera, chrome, firefox.

When I try to ad a product in cart from a mobile never work.

Sometimes on product page next to the "add button" the qty. is showed in a standard edit field "not in a spinedit" (dosnt show the up-down arrow)

I reinstaled more times the shop. I use 1.7.4.4. brand new, dont modified, dont updated.

Guys, this is most likely a JS error, have a look in the btowser's dev tools->console and see what is it about.
