Good morning:

When the capability "moodle/course:viewhiddenactivities" is allowed for a role , if you try to access to a SCORM module and this module is hidden, it indicates that the resource is hidden and that it can't be shown.

I think the error is on this line of the file " /scorm/view.php":

if (empty($cm->visible) and
!has_capability('moodle/course:manageactivities', $context))

{ notice(get_string("activityiscurrentlyhidden")); }
If we replace these lines for the following ones, it works correctly.
.

if (empty($cm->visible) and
!has_capability('moodle/course:viewhiddenactivities, $context)) { notice(get_string("activityiscurrentlyhidden")); }
