My Mautic version is: 4.15.0 (?)
My PHP version is: /etc/php/7.4/apache2
My Database type and version is: ?
My problem is: I cannot send messages.
These errors are showing in the log:
[2021-05-20 01:10:07] mautic.NOTICE:
Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: The “swiftmailer.transport.real” service or alias has been removed or inlined when the container was compiled. You should either make it public, or stop using the container directly and use dependency injection instead. (uncaught exception) at /var/www/html/mautic/vendor/symfony/dependency-injection/Container.php line 275 while running console command
[2021-05-20 01:10:07] mautic.WARNING: Command

Steps I have tried to fix the problem: I’m not sure where to start.
