Sorry for the delayed response but we appear to have solved this on our site
If you go to Edit your Application in Facebook, under the 'Connect' tab theres a 'Base Domain' field.
In here for example if you have <!-- w --><a class="postlink" href="
www.google.com">
www.google.com you would just put google.com.
The problem I noticed for us was it was doing it when the site address was just simply <!-- m --><a class="postlink" href="http://***.com">http://***.com, but never when it was http://
www.***.com. This solves it!
