Error Message When Adding a User
This is generally a browser-related issue. If you have saved your user log-in and password when you log-in, your browser is using the auto-fill feature to populate the username and password fields. You will need to disable any usernames/passwords that is saved in passwords auto-fill within your browser that are associated with the log-in to your Moodle site.
For example in Chrome, you would edit autofill entries and delete any that are associated with your Moodle site. (If you have a test student account or test teacher account saved you must delete those as well; otherwise, they will be displayed when you try to enter a new user even though you have deleted your own log-in. Once you’ve deleted these do not let your browser save your username and password when you log-in or if you do save just delete your user info from your browser when entering new users.
