It's on a Linux Shell as far as im aware. I used the command
lynx - dump
http://my-url/real_cron/24hour.php
I was advised to use this and so far no errors in the emails. Although my site is going very slow and the hosting company have done tests which have come back stating the site takes approx 2 seconds to load a page.
Any reason why my site could be going slow?
Thanks
