I'm trying to set cron from cpanel. I use that command 0,30**** wget -q -O - .php?doing_wp_cron in the cron settings of siteground cpanel. But it seems not to work. Plugin stop to work.

I'm using also "WP-Cron Status Checker" plugin to check if cron is working. If I use the string .php?setcronjob on browser, the cron work perfectly and is detected by plugin, but with the cpanel scheduler, it is not detected and plugin aren't working. What to try?
