Section store heading not adding to cart

[Goodlivingonly]

I purchased a section off section store for a new heading on my website but now the add to cart function isnt working on my products page.

That's the main issue so customer scan purchase, secondary to that is having the customised header available on all pages not manually adding and adjusting to each page on the site which I've half done on www.goodlivingonly.com

I have reverted the website back to the old version for now as people can't purchase. The new header is a section add in, so it seems to be conflicting with something to not allow add to cart. I've removed and readded and that hasnt change it, any other suggestions? Thank you
