Crontab Error

[thinkbsd]

Can someone please help me out on this one. I'm getting a parse error when clicking on the 'crontab' icon logged in as an admin. Here's the output:

Crontab() constructor failed: Unable to create Crontab entry: parse error

0: /psa/admin/plib/common_func.php3:174
psaerror(string 'Crontab() constructor failed: Unable to create Crontab entry: parse error')
1: /psa/admin/htdocs/sysuser/crontab.php:79
