Cron. Operation not permitted

[aropan18]

Hello,

My all previously added cron jobs have disappeared. When I try to add "/usr/bin/php -f /home/aropan/public_html/update.php >> /home/aropan/public_html/logs/update.html 2>&1" every "*/15 * * * *" I get:
Error
/usr/bin/crontab: error renaming /var/spool/cron/tmp.XXXXVx57qN to /var/spool/cron/aropan
rename: Operation not permitted.

What is wrong?

Your old cron jobs were removed because they broke the one cron per 5 minutes rule we have on free hosting. Both of those crons went off on the hour, which is more than one cron per 5 minutes. Beyond that, I'm not entirely sure what's happening with that error. Are you editing the cron jobs via cPanel or some other method?

What can I do?
