A couple of days ago the plugin has stopped working

A couple of days ago the plugin has stopped working and is now posting incorrect links to facebook - like this: http://afbhs.co.nz/2013/1test/?fb_source=pubv1
The actual page is here: http://afbhs.co.nz/2013/mack-aerialscope/1test/

No settings have been modified, and the plugin has been updated to the current version.

It used to work perfectly.

THanks,
Brendon
