Hey…
there is a bug in the pagination class or so I think. 

When I set

to something lesser than 2… it puts a previous link on the first page with a negative value (The value depends on what you have you $config[‘per_page’] set to).

I prepared a little demonstration on my webpages Show me the bug

P.S. I would even suggest a little restructure of that class to make it easier to customize… everything is just in one big function
