Improved Cron is intended as a simple solution to limitations of the Wordpress Cron system. For the average user, it is simpler to just install a plugin than attempt to set up a server level cron job.
When you start Improved Cron, you're starting two separate components. The first is a PHP background process that runs indefinately, takes very little resources, and 'wakes up' every 60 seconds so it can simulate a visit to your site and ensure that Wordpress Cron runs. The second component is a WP Cron routine that runs every 10 minutes and ensures that the PHP background process is still working.
Start: Click the 'Start' button. When the page refreshes you should see the state changed to 'Running' and the time of the next visit to your site will be indicated.
Stop: Click the 'Stop' button. When the page refreshes you should see the state changed to 'Stopped' and the time of the next visit to your site will be blank.
Refresh: Click the 'Refresh' button. When the page refreshes you should see the current state of the background process with all the dates and times updated.
Possible Intervals: This is a table of currently available intervals. Wordpress does not allow intervals smaller than 60 seconds. Plugin and Theme developers can register extra intervals as needed.
Scheduled: Currently scheduled tasks ( also referred to as 'hooks' ), how frequently each hook runs, and the next scheduled run time. Plugin and Theme developers can register extra hooks as needed.
Just deactivate the plugin. The de-activation routine will perform a stop action before deactivation completes.
