I am trying to change the email in either one of them so they are unique addresses, but it will not let me.
I tried selecting a different email from the drop-down options in admin panel -> settings -> Default System Email and it gave me the error message when I tried to save it.
Then I tried changing the admin panel -> settings -> System Admin Email Address to a different email, but it also give me the same error message when I tried to save it :-(
Therefore I cannot save either one due to the error message
Is there any other way to change the email?
