Topic: need help

Here is the link I am dealing with

uniqueevents dot org /wedding_gallery/mountain_lake_view/lauren_travis/

It has been a few years since Postcardviewer was implemented with this site so I'm a little rusty on it's in's and out's. I read in some posts where people had replaced older snippets of code with newer ones and I did this with this particular page to no avail. This issue seemed to start occurring after migrating this domain over to a new server. I don't know if a file got left out or what. Any help is appreciated.
