Unity Splash screen with webgl build

I have unity pro at work and currently we're on 5.2 of unity building for a webgl platform. Everything works fine except when we push a build out without a splash screen we suddenly get an error. "An error occurred running the Unity Content on this page. See your javascript console for more information" and then produces a long stack trace. However, checking the box for the splash screen and then uploading everything works fine again.

Has anybody else encountered this for webgl? It doesn't matter which browser is used from what we tested. It works with the splash screen but errors out if we uncheck the box to include it. Thanks for the help.
