Hay, for first sorry, for my very bad english ;)

And to your question:

You must run a client as prefix for your cronjob how:

* * * * * wget http://tutorialcow.com/Resources\%20_Blocked/Session/Change_Salt.php

in my opinion is:

* * * * * php -c /var/www/yourDirectory/Resources_Blocked/Session/Change_Salt.php

the best you can do, if it's file running on localhost

You need to do something with that http:// address. I think what you want is to execute the PHP file, so I'd recommend

• • * * * wget -O - http://tutorialcow.com/Resources\%20_Blocked/Session/Change_Salt.php > /dev/null

• wget gets a URL

• -O - redirects the output from a file (~/Change_Salt.php) to stdout

• /de
  v/null throws away the output sent to stdout

If there are errors, you'll receive an email from cron.
