Bugs in content types

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.

Hi, this most likely means a PHP error. Check your web server's error_log file for any messages. 

If there's nothing there try to temporarily add the following settings to your config.php and then try accessing one of the broken content again and the error should appear:

@error_reporting(E_ALL | E_STRICT);   // NOT FOR PRODUCTION SERVERS!
@ini_set('display_errors', '1');         // NOT FOR PRODUCTION SERVERS!
$CFG->debug = (E_ALL | E_STRICT);   // === DEBUG_DEVELOPER - NOT FOR PRODUCTION SERVERS!
$CFG->debugdisplay = 1;              // NOT FOR PRODUCTION SERVERS!
