Prestashop 1.7 generating duplicate content in HTML

[Solutions]

Hello, I have a problem with my store. When I enter the product page of some products, I'm getting the following error:

 

Due to this, when I click the quantity button to buy two products for example, it creates a duplicate of the form, see images below:

Before clicking

 

After clicking

 

Any idea on how can I solve this?

It is not happening on all products.

 

Thanks!!

Hi,

I don't think it is possible to write here a good advice, it would require looking at the actual code.

However, this problem should be solved by your theme developer. I would suggest contacting them.
