Wordpress toolkit php mailer error

Petar
Hi, I have WHM with disabled php mail() function because security reason, but looks like that make problem in WP installation with Wordpress toolkit. When I run installation process of new WP installation, I get error: WordPress was installed with errors: Fatal error: Uncaught Error: Call to undefined function PHPMailer\PHPMailer\mail() in /home/my_account/public_html/wp-includes/PHPMailer/PHPMailer.php:874 Stack trace: #0 /home/my_account/public_html/wp-includes/PHPMailer/PHPMailer.php(1902): PHPMailer\PHPMailer\PHPMailer->mailPassthru('admin@mydomain...', 'New WordPress S...', 'Your new WordPr...', 'Date: Tue, 28 D...', NULL) #1 /home/my_account/public_html/wp-includes/PHPMailer/PHPMailer.php(1642): PHPMailer\PHPMailer\PHPMailer->mailSend('Date: Tue, 28 D...', 'Your new WordPr...') #2 /home/my_account/public_html/wp-includes/PHPMailer/PHPMailer.php(1473): PHPMailer\PHPMailer\PHPMailer->postSend() #3 /home/my_account/public_html/wp-includes/pluggable.php(542): PHPMailer\PHPMailer\PHPMailer->send() #4 /home/my_account/public_html/wp-admin/includes/upgrade.php(619): wp_mail(Array, 'New WordPress S...', 'Your new WordPr...', Array) #5 /home/my_account/public_html/wp-admin/includes/upgrade.php(117): wp_new_blog_notification('Born To Be Wild', 'http://mydomain...', 1, 'The password yo...') #6 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/core-command/src/Core_Command.php(618): wp_install('Born To Be Wild', 'admin', 'admin@mydomain...', true, '', 'XlkS^n...') #7 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/core-command/src/Core_Command.php(401): Core_Command->do_install(Array) #8 [internal function]: Core_Command->install(Array, Array) #9 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/WP_CLI/Dispatcher/CommandFactory.php(100): call_user_func(Array, Array, Array) #10 [internal function]: WP_CLI\Dispatcher\CommandFactory::WP_CLI\Dispatcher{closure}(Array, Array) #11 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/WP_CLI/Dispatcher/Subcommand.php(491): call_user_func(Object(Closure), Array, Array) #12 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/WP_CLI/Runner.php(399): WP_CLI\Dispatcher\Subcommand->invoke(Array, Array, Array) #13 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/WP_CLI/Runner.php(422): WP_CLI\Runner->run_command(Array, Array) #14 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/WP_CLI/Runner.php(1214): WP_CLI\Runner->run_command_and_exit() #15 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/WP_CLI/Bootstrap/LaunchRunner.php(23): WP_CLI\Runner->start() #16 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/bootstrap.php(77): WP_CLI\Bootstrap\LaunchRunner->process(Object(WP_CLI\Bootstrap\BootstrapState)) #17 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/wp-cli.php(27): WP_CLI\bootstrap() #18 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/boot-fs.php(17): require_once('/usr/local/cpan...') #19 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/wpt-wp-cli.php(31): require_once('/usr/local/cpan...') #20 Command line code(1): require('/usr/local/cpan...') #21 {main} thrown in /home/my_account/public_html/wp-includes/PHPMailer/PHPMailer.php on line 874 Error: There has been a critical error on this website.Learn more about troubleshooting WordPress.

Is possible to disable send mail notification during the installation, or change PhpMailer settings to SMTP or something other to bypass this problem ? In documentation I didn't found anything. Thank you.

    Hello! The following article should help.

    Thank you @cPanelAnthony but that is not possible because users manage own installation. No other options?

    The only other option at this time would be setting the domain to PHP 7.4 temporarily.

    But that also is not option because all PHP version on server have disabled mail() function.

    The PHP 7.4 should work fine even if the mail function is disabled, since this issue is only with the PHP 8 at this stage. It has been verified that this is due to a change in the way PHP 8 handles 'disable_functions'. Prior versions of PHP would throw a warning when a disabled function was attempting to be used. In PHP 8 and later, attempting to use a disabled function will throw a standard error for an undeclared function with "Fatal error".

    I guess (and baring in mind it is 3.30am for me at the moment) if you use the PHP auto_prepend_file setting in php ini to load in a file which has a dummy function mail(...
    then the problem might be reduced (you could also make the function call PHPMailer).
