I'm not getting any errors, js or otherwise. Nothing in firebug console either. The DOM add/edit links are basically just behaving like they don't have click event handlers on them to fire the href link within a lightbox.
Looks like jquery plugin livequery has been removed, thought that's all I could find tbh.
Changeset 105267: "Removed jquery.livequery as a Requirement from LeftAndMain.php, its only necessary in SecurityAdmin for MemberImportForm.js now."
I can try including it and see if it makes a difference, but I'll be on the road for the next 3hrs so won't be until later this arvo.
