Crash report spike

This app crash report just spiked over the past few weeks. I haven't changed anything in my app:

What is your WebViewer loading? Is this from local html file??

[Husain]

It's a page that contains javascript to track visitors from Google analytics. The page is hosted on my website

Apparently, it seems like its trying to load some resources and is having issues on loading it because its not there. Do you experience this with regular WebViewer loading other URLs??
