Zerif Pro Help! Testimonials page shows blank and need things centered

Hi,

I’m working on a small business site with Zerif Pro. Somehow, along the way of customizing, my testimonials page (which I have renamed as Locations) is no longer working. It’s not checked to be hidden, and on the widgets page, everything is there (text boxes and photo slideshows) but it doesn’t show up when I hit customize. Also, I can’t get my page to load at all when I click “View Site.”

I’m also getting frustrated with the portfolio section.. Is there anyway to be able to move what you want to different columns side-by-side or center items like my 3 portfolio pictures? Please help, thanks!

Maybe I just don’t know enough yet, but this theme hasn’t proven to be as customizable as everything claims…

Here is my site…Not sure if you’ll be able to view it since it is a temp site.
