Hi,
Regrettably I don't know TalentLMS, so don't know the exact answers.
Can I assume that 'advancing to the next module'somehow depends on the outcome of a previous module? As Xerte SCORM packages do not support sequencing, I suppose this is the way it works. Can you please confirm that?
If that is the case, than probably the results are not written back to TalentLMS in such a way that advancing to the next module is happening. It would help me (one of the authors of the SCORM code of Xerte) if TalentLMS can explain to me why the issue is with the authoring tool. I.e. can they indicate what TalentLMS is expecting and is apperently not happening? Than, I can have a look.
Some other things you might want to check:
- Is this particular course embedded differently?
- Is the issue the same on all browsers? (Chrome changed the way unload events are handled some time ago)
- What version of Xerte are you using?
