Hello there,
i´m having a weird problem trying to use the postman plugin.
Whenever i try to enable it, it gives me the above error (Postman: wp_mail has been declared by another plugin or theme, so you won't be able to use Postman until the conflict is resolved.)
I already tried to disable all plugins, activate another theme and even update the theme i normally use.
None of these steps fixed the problem, i can not send any mail from wordpress.
I attached the postman diagnostic, any help is much appreciated.
