    Just upgraded WP Mail SMTP to the latest version. We added the password to our wp-config file as recommended but the contact forms won’t fire unless we turn OFF authentication.

    Here’s the error file:

    There was a problem while sending a test email.
    The related debugging output is shown below:

  • Hi,

    Just experienced the same issue a few minutes ago. Then I removed the ‘suggested’ definitions from wp-config.php file and defined the password in the plugin’s settings form. BINGO!

    Hi,

    We are aware of this problem. It will be fixed really soon.
    For now you may consider turning off the auth, but once 1.0.3 will be released – turn it on again.

    Thanks. I turned off the auth setting and emails are now transmitting.

    I can’t turn off auth with O365 ?? so, looking forward to the update!

    Hi!
    I have the same problem and can’t turn off the auth neither.
    I’m using version 1.2.3, so it’s the latest update from yesterday.
    Is the problem still there or is it my fault?

    Here’s the Errorlog from trying to send a test-email:
