I'm usinh a Prestashop 1.5.4.1, and I would like to call a module in other module (precisely I need to use slider module just above the home featured products). I tried to call it via
include file='../directory/module.tpl'
but always I get only blank page without any code. I also tried with different ways of directory statement, but always the result was the same. Is there any possibility to include new module in correct way?
