I have been working on a facebook share button for my website for three days now and I am having a hard time to get it work.
I tried several things and I think I am close. Below, I post the code I use. If you thing you understand what my error is please let me know. Also I have posted a screenshot of the share window in which the meta information is missing.
On the image you can see that the meta tags are not presented. e.g the title, description, etc.
