Password unmask checkbox is not displayed

Go to any course Enable self enrolment Click to edit the self enrolment settings Enter a password Make sure you can tick/untick 'Unmask' to show/hide the password Save the password Login as a student that is not yet enrolled in the course Browse to the course and self enrol When the password is asked, make sure you can use 'Unmask' to hide/unhide the password in the input field

I've found another fix for this by editing: lib/form/yui/passwordunmask/passwordunmask.js I've added a check, if the parent note actually exists (which is not the case when students enrol themselves (/enrol/index.php)). So far I can't see any negative side effects from these changes: original: //Insert unmask div in the same div as password input. node.get('parentNode').insert(unmaskdiv, node.get('lastNode')); changed: //Insert unmask div in the same div as password input. if (node) { node.get('parentNode').insert(unmaskdiv, node.get('lastNode')); }
