$likepath = drupal_get_path_alias($_GET['q'])

Hi,

I've had a problem with AJAX loaded content. The like button liked the url of the ajax callback page this is because drupal_get_path_alias($_GET['q']); on line #32 of the module.

Why aren't you using $likepath = $node->path;? Is there a particular reason for this?
I have changed the code and Facebook now correctly points to the node->path url.
Patch attached...

Cheers
