Order email not going. Cron job error

[mzeeshan00]

Hi,

Suddenly my order emails are not working and i have to manually go and check web orders. I am getting the following cronjob error. Can someone guide me (keeping in mind that i am not a techy) so that i can solve this problem? Help will be much appreciated.
