pagination using query strings despite not being specified

[eluser]developer10[/eluser]
[quote author="umbongo" date="1287780372"]I am using the pagination class and it is appending '&per_page=20' on to the end of my URLs instead of /20/ or whatever. This is despite me not having set $config['page_query_string'] = TRUE. It continues even despite setting it to false.
There is also no pagination.php in /config.

pagination.php should be residing in CI's main folder "/libraries"
