Please, I am getting crazy with the pagination class :(

Thanks, really! This helped a little... You're right, now it works. Anyway it adds /index/ to the pagination links, something which I completely don't want to happen

How should I do it, without adding $config['base_url'] = site_url('articles/index');

I want my pages to be
site.com/articles/2
or
site.com/articles/page:2

but without /index/
