I have problem when sharing posts (only posts) on Facebook, which is that there is no image or title or any thing but the blog link, while at the same time, I can share pages without any problem. I don't know why this is happening, because the same setting is used for both posts and pages.
If you check the source code you will see the open graph required data.
