Adding 'Add to cart' buttons on second website

[CJ21]

This is the new subdomain I am using since opening up an account for that site https:// cjsequestrian. com/Store
I deleted the other out when I set everything up again.  I have asked my sister to look at my website and she says the buttons are now showing on my site, it seems to only not be showing on my pc when I open it in chrome, so I'm guessing theat issue is not to do with my chrome!
