Cannot instantiate non-existent class: rating in

I get the error:

Fatal error: Cannot instantiate non-existent class: rating in rate.php on line 45

when I run rate.php

and

Fatal error: Cannot instantiate non-existent class: rating in articol.php on line 121

when I run articol.php

I configured everything correctly, I think. The two template files are in template/ and the rate folder is empty. I'm doing this on a lycos.co.uk site.

"Not Found
The requested URL was not found on this server.

Apache Server at grafxsoftware.com "

Why does this error come up when I click on this thread?

Can you tell us if you have added endingl slash on URL and PATH??
