[TYPO3-english] Is Typo3 Facebook extensions (facebook_0.2.1.t3x) still usable?

[Benoit Montereau]

I would like to let my users handle facebook applications and page contents
through Typo3 backend. I found the facebook extensions and installed it.
Everything seems to be ok regarding the installation/definition and adding
content.

Unfortunately, when I try to display the content on facebook, I'm getting
the following error:

FacebookRestClientException

Unknown method

So I'm wondering whether this extension is still ok with facebook
requirement and is usable?

Thank you in advance for your help.
Regards,
