Light box plugins do not function

Hello,

I put a couple of lightbox plugins such as the 'facebook lightbox'. Every plugin of this kind, does not operates in my site. Is this a matter of your theme or by the specific plugin?

Thank you

Hi!

Some plugins may be not compatible with the theme.
Could you give us your website, please.

As I can see the theme works properly with the lightbox plugin that is already installed.
