My site ccorch.org was built using Joomla 4 and recently upgraded to Joomla 5. User accounts are established only by an administrator and MFA is enabled. Everything has been working fine for several weeks until recently it stopped sending 6-digit MFA confirmation codes to registered users.
Now any attempt to login to front end or back end results in the message "Could not instantiate mail function" being displayed somewhere on the login page. The user will then receive an email telling him that he is logged in but he will not receive the necessary 6-digit confirmation code necessary to enter the site.
I have tried changing the global settings for email on the site from php to smtp and also to sendmail. Any of the email states will successfully send a confirmation that email is working but none will send the necessary 6-digit code.
I'm making one more attempt to send this through your firewall without the log file which I tried to include
