Responsiveness Problem !

I can fix the problem with the commande overflow-x: hidden at the end of my layout.css. But it's not very cool because it crashs my text centering.

It's already on your hotstart joomla package so it's not an error from me.

Can I ask a refund if you do not find any conclusive solution ?

Try:

.contentrow .container div.item, .contentrow .container div.item-page {
padding:0;
}

THANK YOU ! FINALLY IT WORKS.
