Shares blog, not post

What exactly to you mean? Can you give URL of your website so I can take a look.? You can send it here if you like.

She means when adding the code to a loop for an archive page, like news archive, it shows the page information, rather than the individual posts. I am having the same issue. Please look at the link below:

I cannot reproduce this problem on my test blog.
Can you post the code that you use inside a loop?
What theme are you using?
