[Calcifer1989]

Hi to all ,I Need help to configure my Landing Page... I'v newbie of PS.. 

My URL www.o2-med.com/prova Is for a Landing Page , i'd like to have a Page with only contenent +right & left column. I've tried disable evrey module's hook from "position" on My pannel, but as you can see , i still have a navbar + some header component. Is there a way to remove completely header + navbar + footer? And show only contenent of My Tpl file + right and left column?

 

If Yes please guide me step by step thanks !
