No caption with TosRus script effect

Hi,

With TosRus script lightbox effect selected, images from gallery doesn’t have any caption or title, just : “lightbox[pp_gal]”

It works with other script like SwipeBox or PrettyBox from your plugin, but I prefer TosRus.

So do you have any idea about this problem?

Thanks,
