I'm having a bit of a problem sharing blog posts on Facebook -- either manually or via a plugin.
Previously, trying to link to a post from Facebook would show the post title and excerpt, the site name and url. Now it instead just shows the site name and an url. (Actually it used to show a redirecting domain name and now shows as the url that of a subdirectory on my main domain.) Or it shows the correct details but for a much older post.
I've tried manually adding new open graph tags but that didn't seem to work.
Would anyone possibly have any suggestions of how to correct this? Is it even a problem at the WordPress end of things?!
