Dallas here from Shopify's Social Care Team.
Are you able to share a screenshot of your blog page in your Store Admin and then could you share a screenshot of the front end of your website where the blog should be.
If you could also share the URL to your store, I'd love to see if this is a local issue on your browser or if it's just not showing up.
Is it possible that you have it published, but for a future date?
With more information, I'll be happy to see what I can do to help you out here.
Blogs post for e-commerce is a useful way to increase traffic to your site. So can you describe your problem more specifically? Such as providing us some URL to your blog post or your store, how did you add the blog post, etc...
Btw we did a resource on how to add blog post on Shopify, you can read it to check if you added your post in the right way or not.
Have a good day ^^
