Don't understand why page buttons don't advance the page

I’m new to this Highend Theme, and pretty much an HTML noob.
I’m having a problem understanding why the page buttons at the bottom of a gallery don’t switch to the next page. As I add more content to the gallery, I can see the number of pages available go up (now 3 pages), but if I click on a specific number, or the advance button, it just stays on the same page.
This is basically a small modification of one of your Theme Demo pages to which I’ve loaded content. Most of the code isn’t visible using Visual Composer, so I have no idea how to access and fix that button.
The URL for the page in question is:
http://www.sourlandwoodcraft.com/?page_id=1983#038;paged=3
(I can send you login credentials if you instruct me how to do it privately)
Thank you!
