    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.

    Hi. Your diagnostics are suspicious

    WordPress wp_mail Owner: /var/www/vhosts/mysite.de/httpdocs/wp-config.php

    Open up this file and see what’s in it. See if you see something like the following

    function wp_mail

    That’s not part of the normal WordPress distribution.

    Hey there,

    thanks for the reply.

    Actually there was a line “function wp_mail(){// DO NOTHING}”, although i have no idea who put it there.

    Anyway, i removed it and now WordPress is able to send mails once again.

    Thanks for your help, have a great day 🙂

    Probably your host put it there to prevent you from sending mail.
