[theme: canvas] issue "older post" buton

I′m using canvas 5.1.1 (woo) and I have configured “magazine” style for main blog page.

You can see it in https://www.felicityevents.net/

The problem is that I can’t browse older posts because the “older posts” button always charges the same main page.

If I configure it to show page numbers instead of “older /newer posts” button i get the same results.
