H5P activity & content replaced by blank page after editing
Editing existing, functioning H5P Interactive videos causes them to disappear. On saving, a blank screen is displayed.
When the activity is opened again from the course menu, the same white screen is displayed. The original activity is no longer available.
H5P Interactive video activities continue to function normally (until edited), then the issue aoccurs.
All other activity types (non H5P) are functioning as normal.
