Here's an interesting one. I'm not sure when this happened, because I haven't needed to add a CRON for a while. Went into cPanel tonight to add one and got the following error: /usr/bin/crontab permissions are wrong (6755). Please set to 4755. I fixed the permissions and all seems well, but why would this change in the first place? I don't recall seeing that any of the cPanel updates might have caused this, but that could be the case.
