Vector Map Stopped Displaying

[a-pompei]

We are running jVector Maps 2.0.5 on a website at https://unausa.org/chapters.

The map view is no longer displaying a map or the map markers and returns a Server 500 error and displays a message on the website stating, "There was an error processing your search, please try again."

The list view works just fine though.

Any assistance would be greatly appreciated.
