Problem with pagers on marketpress

Hello people,
On my site marketpress doesn't display pagers ANYWHERE.
I'm building a custom theme so that must be it, but I just can't pinpoint the problem!

My theme is a roots child theme and I've got it right here if anyone is kind enough to take a look at it...

I'm modifying the markup marketpress outputs, so I've copy-pasted and edited some functions from the marketpress-includes/template-functions.php in my theme's functions.php.

It's not finished yet, I'm just stuck trying to get pagers to work. Ideally I'm trying to make them infinite-scroll-like but for the time being I can't even get them to appear normally.

A demo site is here: http://makrismusic.shoppers.gr/ (yes, it's in greek)
