styles, icons, images and css don't showed

Hi,

I've installed ocsinventory-ng but in the browser when i surf through the ocsreports site i can't see the styles, i can only see a minimal interface all in white and gray colours. Also i can not see the icons and other images.

What can be happening?

My installation is last version from the .tar.gz2 in debian 8 jessie with apache2.4

Thanks.
