Cron Job not working

[asn]

Sir, my cron job is not working.

When I check in ISPConfig monitor tab
Under monitor tab - ISPConfig Cron - Log, I see following output

mkdir: cannot create directory `/var/www/clients/client1/web1/var': File exists
mkdir: cannot create directory `/var/www/clients/client1/web1/var/run': File exists
mkdir: cannot create directory `/var/www/clients/client1/web1/var/run/mysqld': File exists
ln: creating hard link `/var/www/clients/client1/web1/var/run/mysqld/mysqld.sock': File exists
invalid shell, /var/www/clients/client1/web1/bin/bash does not exist
usermod: no changes

Why this problem comes. Please help me.

Thanks & Regards
