Emails not sending automatically

My emails send manually and not automatically.

I tried adding:
define( “DISABLE_WP_CRON”, true );

I get this message:
Your WP Cron is disabled. If you want to use WP Cron, open file wp-config.php and delete row define( “DISABLE_WP_CRON”, true );.

When I delete the row, I get this message:
Your WP Cron is enabled. If you want to use Cronjob server, open file wp-config.php and add row define( “DISABLE_WP_CRON”, true );.

They seem to contradict each other.

Either way, automated emails are not sent.

I have WP Mail SMPT installed and working.

Any ideas on how to fix this?

Thanks.
