Problem with pagination and 404

Hi,
First, I want to thanks a lot the plugin author, because this plugin help me a lot ! 🙂
I have a problem with pagination. All pagination works good with normal categories but when I use it on archive event page (by day archive), the pagination doesn’t work anymore, I got a 404 page. I tried to alter main query to make it work, but nothing seems to work :-/

Here is an example : http://qataractu.com/evenements/2014-02-11 when clicking on page 2

Have you any idea about the problem ?

Thanks
