Add to cart button going to email

Hi

Trying to explain this as best I can. I have a site which I have built from scratch, completely new install and latest zen cart software. Additional plug ins are easy populate, recover cart sales and will be simple seo urls.

Now when looking at a product and clicking the 'add to cart' button instead of adding to cart it starts loading up my email system so as to send an email to the site owner.

Now this doesn't happen on all the products, its a tad random.

Is there anyway I can fix this? Or any idea why this happens.

Site is https://www.motorcyclebikedecals.co.uk

Thank you

I can't make that happen on your site. Is it possible to turn off that 'Share' thing and then see if you can duplicate the problem ?
