Facebook share modifies path to shared article
If I share an article through facebook, say located at www.domain.com/sub1/sub2/article.html it gets shared as www.domain.com/article.html
using: <a class="addthis_button_facebook_like" fb:like:href="http://www.domain.com/sub1/sub2/article.html" fb:like:layout="button_count" fb:like:action="recommend"></a>
Not sure why it strips off the subdirectories.
Do you have any Open Graph tags set up on the page? those would take precedence over the configured fb:like:href parameter.
