PhP Errors!

[sheepy]

Hey there.
For some reason i started to get errors on one of my websites an as i dont know much php im pritty much pickled!
This is my site where the errors are coming up. http://www.theory-guild.co.uk/raids/index.php
Some guy said to me its because there isnt enough space to store the tmp files. So i laughed at him saying i have like 10gb of space an 1000gb of bandwith. He just replied contact your host.
So anyone have any ideas?

Thanks in advanced
Sheepy
