customizr lightbox

Hi,

I’m new at WP. I use Customizr theme. I found it really nice. Everything was OK on lacalhost but when I put it on the server, I lost my fancy gallery. Whatever the setting, if you click on a picture, it opens – in teh same window – a black frame with the picture inside, no arrows, no links back or forwar. I changed the pop up setting in the appearance menu but useless

has someone get the same trouble ?
thanks
