ok.. the right cron-job line in your picture is the third line
wget -p -O /dev/null http://vudl-pk.tk/ow_cron/run.php
(the first and second line cant work)
Next step, try to confirm your cron-job to
2 * * * *
wget -p -O /dev/null http://vudl-pk.tk/ow_cron/run.php
because it is possible the your cron-job engine dont understand the first * and do nothing.
The "2" is for two minutes, if this dosnt work make a higher time e.g. 5 minutes.
Many Webspace Provider dont like short cron-jobs times (must be see in the Webspace Provider knowledge base)
More Information here
http://docs.oxwall.org/install:cron
There are Information for make cron-job to PHP action, that have more function at the oxwall system (read this for better understand as my english here ) and can resolve your problem, when your provider dont like loopback requests.
hope my english is a little bit to understand
