Hikashop social network plugin

I really can't understand how to keep linked my hikashop product page (trought the social network plugin) and my facebook page.
The like button works fine but no informations are passed to the facebook page. I think this should be done trought the
"facebook admin" parameter in the plugin page but I don't know what to write there. I tried with all the methods
posted by chaka in this thread but none worked.

I miss something.
Thanks a lot

Are you sure that you have entered the good ID for the facebook admin parameter ?

Facebook can take some times before updating the page.
