Could not instantiate mail function error
If you encounter this error, please make sure that the email settings in Joomla! Global Configuration are correct. To test them, we suggest that you create a new user account and check whether the registration email has been sent.
If the above settings are correct, verify that the recipients' emails are valid email addresses. Check for any mistakes in the email address(es) or in the placeholders (if you have used them).
The correct email separator (if you have multiple recipients configured) is comma (,). If a incorrect separator is used this will lead to a error and the emails will not be delivered.
