Blank screen after update
Sure I have seen this mentioned in the forum before but I cannot locate it now (the search function is awful).
If I update my content and re-export it to SCORM, after updating the content on my LM...
Hi Paul,
We also have Moodle 3.9 and are running into this problem quite frequently. Having approx 80 000 users, it's quite the hassle.
But you said you're not running into this problem anymore with having a ''base'' course and duplicates as backup courses? I didnt quite understand how that worked exactly? You have a base / main course from where you do all your updates and export, but what purpose do the duplicates then serve? And wouldnt you run into the blank error if the changes on the base course were too big / severe that it messed up the location messaging in the scorm?
I might've missed something quite basic, sorry if thats the case.
The duplicate courses are backups of the course that we are developing (e.g. something goes wrong we have a copy of the previous version). We looked at the lesson id of the 'base' course and could see that they remained consistent for a given lesson when we added new lessons to a section. The lesson ids change for all lessons when you duplicate a course. Its the change in lesson ids that causes the blank screen - hence the need to stick with the 'base' version of the course.
What we are finding is that the lesson progress data is not accurately recorded (see post). We have received an email from Articulate this week stating that:
"Articulate have designed their courses so that when course files within an existing course are updated in a LMS or Web server, learners who previously started the course won't be able to resume where they left off. While as described, there are some situations in which the LMS can preserve the learner data while updating the course, it isn't a guarantee that their courses will work each time after the update. That is because the course structure changes each time you make changes to it, especially when removing or adding lessons to the course."
Clearly this is a bit of problem and seems to be an issue with the scorm 1.2 data limitation (Articulate 360 - Articulate Studio: Exceeding SCORM Suspend Data Limits - Articulate Support).
We have tested updating the 'base' course adding / remove lessons / restructuring and the course works when you upload it to the LMS - the lesson progression data doesn't. We are now at the stage of adding in the java script update (see this thread) that results in the course always opening at the overview page. The aim is to use the overview page to post messages to learners providing advice on the updates along with instructions.
Happy to meet up via teams if you would like to discuss further. P
Alright, thanks for the clarification. I've been testing a bit myself and was under the impression that if you made too severe changes, i.e deleting lessons that were previously completed it would result in a blank screen.
If you have the time it would be great to have a teams meeting to discuss for further clarification.

Hi Bo,
When I changed the structure of a course (added and deleted Lessons) after students had already started using the course, it resulted in a blank screen when they logged in after the course was updated in the LMS.
Yeah, this is my experience aswell. we might just have to use the .js edit provided by Michael on the top of this page. And probably avoid using Rise in the future.
