I've just upgraded our demo site to A+ v1.4.4 and I've identified a couple of potential bugs and would appreciate if you could confirm.
1) If you activate the 'Locations' and 'Service Locations' Add-On and then try and edit an existing Service name in the Services tab it doesn't save the change.
If you then deactivate the 'Service Locations' Add-On it works fine.
2) If you activate the 'Shared Resources' Add-On it dramatically slows the admin side of A+. I tried editing the name of an existing Service with this Add-on activated and it took approx 20 secs to make the change.
I didn't try the front end.
