FIXED - Deleted and recreated the product page, using the same URL to preserve search status and precvious sales.
I was editing the product title SEO at the bottom of the page and now the product page is not loading.
I can’t even seem to link the product here. The item is
Joma Jewellery Bracelet - A Little Proud of You
https://curiosgifts.com/search?q=Proud+of+you&options%5Bprefix%5D=last
Other pages seem to be fine. The product appears on the site search going to the product page itself is the issue.
