its becoming a bit of a headache this isnt it? I've saved the code above as a .php uploaded it to my server, created a cron job linking to that file.. but still no luck

I've spoken to my host and they say everything is fine on the server side. I'm just thinking what I could do, i really want these feeds to auto post, otherwise i'm going to be constantly selecting "run now" every hour which i don't think i could do.
How about me giving you access to everything, on my vbulletin and my cpanel to see if you can see anything wrong?
Really appreiciate the time you've given me!
