Add to cart not working in Apple products

[bennik]

Hello every one.
Can a very kind person please help me with a problem I have that is killing me.

I had a developer who made my website, since I have no clue about programming, and since he did a very bad job, I have had many problems. 
I have had problems with the ad to cart not working at all from apple products, neither from Firefox nor Internet Explore . He fixed it and somehow it just stopped working 

I have not changed anything at all. The only module I have installed is the Google analytic for Prestashop 1.7. I am not sure if it is this that causing.
Any way , I am loosing few possible sells because the ad to cart is not working at all. 

Please can any one help me?   I really hope so  
I am using Prestashop 1.7.6.2  and my website is www.benush.es
Please tell me if you need other information. 
Thanks in advance
