I swear I've read something in the past, but I can't find it now - does it mess up cPanel's handling of cron jobs if you manually edit the crontab? I have crons working on all my sites except one - when I add the commands in cpanel, they just get wiped out. I'm starting to suspect that someone before me may have edited the crontab. Any other possibilities? And if that is the case, how do I fix it? Thanks!
