Ted here from Shopify, thanks for posting your query!
I'd need to replicate or view an example of the error you're seeing to help you here. Could you share your store's URL with me here and I'll take a look? If you would prefer to chat with our support directly, our live chat, email and callback support can help you here too.
Let me know how this goes and if there is anything else I can help you with, I'm happy to help!
