@hurencio Thanks for ask help.
I will suggest to the try a new fresh theme copy and check it will work in your store.
If you using not using the Shopify theme then you have to contact the theme author that will help
The second solution you can try another theme too
Can you send me the broken link, I will check it.
If it's in "/admin/products/", this may be due to internet speed, just try again later.
If it belongs to the product page in the frontend, you need to contact the theme, they will help you solve this problem quickly.
Hope it helps!
