MarketPress shop page pagination not working on homepage when using Luke & Sara theme

I’ve setup my MarketPress shop page as homepage and pagination is not working with the Luke & Sara theme. When clicking on the ‘next ’page button or number ‘2’, I get redirected to a page showing this text 'SOMETHING IS NOT RIGHT' and a ‘Take me home’ button below it.

This is only happening when the shop is set as the homepage. I’ve checked it creating a new page and adding the [mp_list_products] shortcode on it and pagination was working ok on that page.
