The Facebook recommend button generator gave me a button for my website but it does not work as it works in the demo of Facebook, it is not popping up the dialog box also not fetching the right image.
I have set all the meta tags correctly and they are rending properly as well.
Here is one example post, http://makinsensebabe.com/ten-video-pictures-explaining-why-everyone-went-nutz-in-spain-last-week/
I have been searching on this issue from a few days now and not getting any suitable answer, not even fetching the right image every time after setting the meta tags.
According to Facebook's Debug Tool you're missing some of the meta tags needed:
Admins And App ID Missing fb:admins and fb:app_id tags are missing. These tags are necessary for Facebook to render a News Feed story that generates a high click-through rate.
