use full path for starts
I would start (as already pointed out) to use full pathname to all of your binaries.

example. Original:
Code:
host=$(grep DB_HOST "wp-config.php" |cut -d "'" -f 4)

Change to:
Code:
host=$(/bin/grep DB_HOST "wp-config.php" | /bin/cut -d "'" -f 4)

Repeat. Also, the host variable above is looking for wp-config.php file (your wordpress configuration file). Your first cd command is:
Code:
cd ~/mysub.example.com

That is NOT an absolute path (it's relative). So cron won't find it.

To find the exact locations of the files, in your CLI just run
Code:
which <binary>

to find out where it is. Such as
Code:
which tar

NAME

       apticron - Generate a mail listing packages which are pending an upgrade

SYNOPSIS

       apticron [--cron]

DESCRIPTION

       apticron is a shell script which generates a mail with a list of all packages currently pending an upgrade, as well as summary of changes -
       using apt-listchanges - to a configurable Email address.

       apticron is mainly intended for automatic notification of pending security updates but can also be used	in  many  other  situations  where
       timely updates are necessary.

       The --cron option is only meant to be used when invoked by cron in order to run no more than once a day.

FILES

       /etc/apticron/apticron.conf
	      Configuration file, Email address to mail and profile for use with apt-listchanges are configurable.

       /etc/cron.d/apticron
	      Cron job for executing apticron daily.

       /etc/cron.daily/apticron

       /var/lib/misc/apticron.cron
	      Time stamp file used by apticron when invoked with --cron option.
