Tira here, from Shopify.
I'm happy to take a look at this here for you. Thank you for posting your screenshot. This is helpful.
I would like to help point you in the right direction or troubleshoot this further. I have a few questions to get us started:
- What is your store URL?
- Have you installed any apps recently on your store?
- What theme are you using on your store?
- Have there been any code modifications made on your store?
- When did this start happening?
- Do you see any errors directly on the cart page when viewing your store from a customer's perspective?
Once I have more information from you, the community and I can take a closer look at your store.
I look forward to hearing from you!
