After the latest changes in the Facebook Like button some user registered a change in the number of pages counted when their website switched to https.
Don't consider the real URL would be rather abnormal for a social button if was not for antoher critical bug i registered which affect its normal behaviour: the like button, despite showing the correct number and apparently working right, didn't allow to like any content, once logged in Facebook, a popup window show for few seconds and nothing allow to confirm the action.
Luckily the patch #11 seems working well, it includes also a patch for Twitter following the hints given by the user natuk in the comment above.
In the meanwhile i try a modify to uniformate the javascript code to the other plugins, apply the patch suggested is highly reccomended!
