Fatal error: Cannot redeclare class ci_exceptions

[eluser]Andreas Vandenbussche[/eluser]
Hi,

I'm setting up a CI site, it's my first one I ever did using a framework and I have to say, it's waaaaay more fun than creating everything yourself.
My problem is: I made a site and put it on my (php5) server and everything worked, today I was moving it to the server where it should be (php4..) but I got an error..
Of course I first googled it but nothing seems to help..
I put everything back to how it was in the beginning, so I hope you can help me?
The biggest problem is that I didn't design this site on my own, someone else started it but due to stuff he hasn't got the time anymore so I took it from him..

the error I'm getting is

Code:

Fatal error: Cannot redeclare class ci_exceptions in /home/beachsho/public_html/nieuw/system/libraries/Exceptions.php on line 27

The site is at this location at the moment..

Thanks in advance for the help and thanks for the magnificent framework

(I'm sorry if I put it in the wrong area but it's my first post here...)
