Prestashops bootstrap slider hidden on mobile devices.

While developing http://laperalimoneraecologica.com I noticed the slider desapeared on small format screens (phones and tablets), didn't even render.

The solution in the end was simple, just had to go to the modules page and enable it for mobile devices wich by default is disabled.

The reason it was desabled by default is that the defauls slider doesnt adapt, but that was easelly fixed by adding:

  #homepage-slider .bx-wrapper img {
    height: auto;
    width: 100%; }

on homeslidder.css line 76.

Hope it helps!
