Masonry Gallery example – lightbox nextgen pro not working properly?

Refer to this documentation: http://www.nextgen-gallery.com/nextgen-gallery-pro-available/#gallery

– the black background and social share / comment icons as well as thumbnails are not showing.
– the images are not resizing to fit my screen.

 

Example of Nextgen Pro thumbnail gallery – same problem as masonry gallery – the lightbox issues – not opening to pro lightbox like examples?

 

 

 

Example of the Pro Filmstrip Gallery – working as it should – as it doesn’t need lightbox.

 

 

 

 

Additional question: Why is there a sidebar showing on this page, when none has been set???
