[yubiuser]

With the upcoming Pi-hole version 6 PHP is gone.

[rdwebdesign]

As explained by yubiuser, the current version in development doesn't use PHP and the PHP code probably won't be fixed.

As a temporary fix, you can hide the PHP deprecation messages in your system adding & ~E_DEPRECATED to error_reporting in your php.ini, like this:

error_reporting = E_ALL & ~E_STRICT & ~E_DEPRECATED

@both acknowledged and thanks

I’ve fixed the php code myself instead of disabling the messages in my server .. I’d rather see them myself …

Look forward to the new version

Keep it real out there
