I agree, the flash is unrelated, although annoying because Chrome is now blocking flash content by default.
Well, the course worked fine for me but my LMS user reported the error and sent a screenshot. This error seems to come up fairly regularly for using taking the older courses on the LMS, so it would be nice to figure out what is causing it and what changes to make to the course to prevent it I’ve reached back out to the user to collect some data, browser version, etc. Would you recommend that I contact my LMS provider? Unfortunately, I have a feeling that they will turn it back to me and say check the course in Lectora.
