Setup cronjobs
Normally cron jobs on the script are ran silently, meaning they run on each page loads & they do things like check expired user plan & send them expiry mails.
If you want to disable the silent cron & use the dedicated cron page, do navigate to your admin settings, on the general tab, scroll down to the section "Disable silent cron" & turn it on. You would have to setup a cron to hit the cron page. Please check the cron example below & change the "http://bio.test" to your real site address with protocol like "http", "https".
