Hi Irene,
I’ve unfortunately been unable to reproduce the problem so far. Would you mind opening your javascript console (https://www.techonthenet.com/js/open_console_log.php) and check whether you see any error message in those cases when sending the results fails? (don’t mind the warning messages about 404 errors)
If you see something about controllers.running being undefined then it means I’ve (partly) identified the problem.
Thanks,
Jeremy
