Today I was working on my course and I moved a hotgraphic from one block to another in the authoring tool
when trying to preview this change, the course was stuck on "loading". I checked the hotgraphic and all the links to the images were gone. So I restored the links, but the preview was still stuck onloading.
I moved to a backup from a few days ago, same problem.
effectively I now lost a few weeks of work if I cannot figure out why I cannot get past the loading screen on preview.any and all suggestions are welcome. this is a serious bug. not being able to solve this means I will have to look for another tool to create scorm courses, because this is a serious reliability issue.
