Course tracking not working in Moodle

Hello everybody,

we have built a Rise Training for our customers at the end of last year, which we exported as SCORM 1.2 in our Moodle LMS. The problem was that the course tracking did not work properly, the progress was not correctly saved. Thanks to the great Articulate support we learned that the course was too huge for SCORM 1.2 and that we have to use SCORM 2004. We followed this advice, although our Moodle informed us, that SCORM 2004 is not supported by Moodle. However, everything worked fine for more than 3 months, without any problems. But suddenly some days ago, one of our customers informed us, that the course progress of his user goes always back to zero after leaving the course. We already run several tests on our platform and we can confirm, that we actually have the same problem with the tracking not working. What can we do? We do not want to divide the course into pieces in order to use SCORM 1.2. Our Moodle host said it is a Rise problem, although my tests in SCORM Cloud were successful. Any experiences or ideas? Would it be an option to use another Standard, i.e. AICC? Which other options do we have? Your help is much appreciated!

Best regards, Rebecca
