This is Dallas from the Shopify Social Care Team.
Blogs don't generally have a login for your customers unless you have added an app that specifically does this. Do you have an app that creates sections for your store that are only accessible to those who make accounts on your store?
I would love to see what it is that you're seeing exactly because I think I may understand what you're dealing with even more if I see a screenshot. Can you add a screengrab of what you see when you click on the link?
If you could also share your store URL in this thread as well that would be much appreciated. Thank you so much!
Wonderful! I'm so happy to hear that.
Please let me know or our Support Team if you ever have any additional questions!
