We enabled AJAX over the weekend on our avteconline.org server, maintained by remote learner. Since then Activity Locking v2.0 has not been working properly. So we disabled AJAX and that took care of some of the challenges but now none of the activities will unlock even after the prerequisites have been fulfilled. We can not make this work no matter what we do. This has effectively SHUT down some of our courses that are based on activity locking so would appreciate help at your earliest convenience. Remote Learner is working on assisting us with this. Can we just blame Shane Elliott? It was during his presentation in Alaska that we learned about this feature, of course he did not advise us to enable it on a production server we just got a little carried away by the moment Thanks for any assistance we can get. You can see an example of this at avteconline.org if you log in using ASTE2008/ASTE2008 and click on the Moodle Boot Camp 2007 course. Click on the Scavenger Hunt Quiz and you will see that you can not access it without first clicking on the Scav Hunt Activity. Even after you click on the activity you still can not get into the Scav Hunt Quiz. We also created a brand new lock and that would not work either. You can also see that the ASTE2008 student can not get into the Tour Quiz even though they earned a 10/10 on the Scav Hunt Quiz as required by the Tour Quiz Lock.
