Hello Othniel,
I am not sure if this was a typo but the correct cron command should be
[gist]
*/5 * * * /bin/wget -o /dev/null "

[/gist]
Notice that there is an asterisk in front of the /5 . Also, you need to check with your hosting provider if /bin/wget exists on the hosting environment as not all hosting providers has the same environment and some hosting companies do not allow the use of wget in the cronjob.
