When first implementing the Login extra following these instructions all functionality was working properly. No changes have been made to any of the login-related code on our end, however, the ForgotPassword snippet is no longer sending emails to the user to reset their password.
Is there any way that can be recommended for how to best troubleshoot this?
So it seems that there is a problem with your SMTP settings.
(These are general MODX settings. Not specific to the Login extra.)
To debug email issues, it’s usually recommended to install the extra QuickEmail.
Also maybe take a look a this page in the documentation (or maybe this page for MODX cloud).
After installing QuickEmail and creating and viewing the QuickEmailCheck resource, the word “Unauthorized” appears on the page where I have added the snippet.
