Hello,

A few years ago I switched the email delivery method from PHP mail to SMTP. I’d now like to switch back, but I’m running into this error:

hash(): Passing null to parameter #2 ($data) of type string is deprecated

The message appears both when I save the settings after changing to PHP mail and when I run the email-settings test.

Environment:

• Invision Community 4.7.20

• PHP 8.1.25

Thanks for your help.

Have you first of all checked with your hosting provider to ensure PHP mail is set up there?

Solved. I just needed to install Postfix and set it up. Thanks! 🙂

Glad to hear things are now working for you
