It appears that all of the SCORM attempts from all of my users ever since I upgraded from 2.3 to 2.4 back in December have the same problem: SCORM status always "Not attempted."
I have tested with SCORM debugging on for different SCOS and different user behaviors, always the same result. SCORM debugging shows no errors whatsoever. There is no sign at all that anything is wrong until I try to look at the tracking data for a particular SCORM attempt, which is unavailable because the status "Not attempted." Strangely, the grade does seem to record even when the status is "Not attempted."
See the image for an example of what I'm seeing. Everything before December 18 records as it should: "Completed" or "Incomplete" with a score of either 0 or 1. Everything after the upgrade (two red boxes) shows the error: "Not attempted" status with an appropriate grade of 0 or 1. But when I view details for that attempt, there are none. Please advise.
I have been using Moodle for about 2 years and upgraded many times. I've searched the tracker and the forums but found no one else with this problem. I apologize in advance if I'm being stupid, but I promise I'm not being lazy. How could it just be me?
