My shop is due to launch in a few hours but I've found a fault.
I'm using the molla theme, when I am on a product page and I click on a variant and add to cart, the item gets added fine.
When I dont click a variant and it's just automatically selected to the first variant and I click add to cart, it doesn't add the item to the cart. But when I press add to cart a second time, it adds the item.
When I click on a product with no variants and simply add to cart, it doesn't work the first time either but works the second time.
Any help would be appreciated! Thanks
Without checking code I don't think anyone can help you.
And to check code you have to hire someone.
