For me, setting DISABLE_WP_CRON to 'true' or 'false' results in the same outcome - Cron does not run. Therefore, I decided to remove it from the wp-config file, and everything is back to normal.
Ideally, it should function according to the correct logic - if set to true, it should not run; if set to false, Cron should run. Enhance should improve Cron configuration and functionality.
