• Hi there, I raised this topic already by email without any solution.
    Meanwhile I set up a complete fresh installation and installed only plugin “contact forms”.

    I received the same error message as in my other WP installation, as this one is a fresh one it can’t be related to other plugins or wrong configurations. WP installation is configured as multisite but plugin is only activated on one network.
    Also both possibilities for sending forms have been tested, without any success.

    For testing purposes I also installed another forms plugin (same page) and this one works without any issues, so it have to be related to your plugin.

    I found two other posts with obviously same error:

    Contact form is not working from outside our network | www.remarpro.com

    Getting Error When Sending Mail from Website | www.remarpro.com
