What is a CRON job?
A CRON job, also known as a scheduled task, is a process that your web server/computer runs at preset intervals. This operation usually does things such as process management tasks, update data, or do backup at the preset time that it is configured to do so. Here are some examples of what a CRON job does: JEM requires the use of CRON jobs to run its daily management tasks and to generate invoices if needed, if any. Please check to make sure your web host supports CRON or some other sort of task scheduler whereby you can run a specific program at least every 30 minutes.
