Imports the comments posted on your facebook fan page (or public profile) to your blog.
For example : 1. if your Facebook Fan Page url is http://www.facebook.com/pages/BlogName/123456, your Fan Page ID is just 123456. 1. if your Facebook Fan Page url is just http://www.facebook.com/pages/MyName/, your Fan Page ID is MyName.
Check the Report table in the plugin settings page to understand where is the problem. The plugin checks the Facebook API every hour (or more if you configures it). However, sometimes the Facebook API is very slow or does not respond. In this case, the plugin will check for Facebook on the next time. If you still have problems, check the forum at http://wordpress.org/tags/facebook-comments-importer
