lightbox not displaying

Hi dear developers,

I just installed FooGallery, FooBox, and responsive lightbox from dfactory…

After creating a single thumbnail gallery and adding the shortcode to my site, I went to check and notice it only links to the single image, no lightbox…
Tried to change different lightboxes… and struggle a lot to find a solution only to get myself frustrated to tears…

So I came here, looked the whole forum and couldn’t find a solution either…

Can you take a look at my situation please…?

Thank you in advance and best regards
