Hello again friends.

This you see I come with a problem in the email configuration, I am using php 7.4, apache2 and the following code in config_inc.conf:

$ g_allow_signup = ON; // allows the users to sign up for a new account
$ g_enable_email_notification = ON; // enables the email messages
$ g_phpMailer_method = PHPMAILER_METHOD_SMTP;
$ g_smtp_host = 'smtp.gmail.com';
$ g_smtp_connection_mode = 'tls';
$ g_smtp_port = 587;
$ g_smtp_username = 'mail@gmail.com'; // replace it with your gmail address
$ g_smtp_password = 'XXxxXXxx'; // replace it with your gmail password
$ g_administrator_email = 'mail.leyenda@gmail.com'; // this will be your administrator email address

and it tells me the error that I attach in the image:
