This has been happening for me since 2011 on whichever version I started out with (can't remember now) so I'm not sure if it's a bug or feature. I always figured it would be fixed on my next update but that never happened. With my latest update to 3.1.2 it's still happening. Basically, I delete a client and everything seems to be gone from them (even their site(s)), however, their cron job(s) never get deleted. I have to go in and do it manually. Here's a quick video showing this: This is a perfect server centos 6 setup. Thank you for any advice in advance. Mike Rogers
