Manifest: Line: 1, column: 1, Unexpected token

I get this error in chrome console…

Manifest: Line: 1, column: 1, Unexpected token. chomemanifest

Ignore or something to think about?

Is this on the desktop or on a device? WebApp or PhoneGap?

Web app running in chrome on pc. I’ve no idea if it happens on a phone. Just an error showing up in the console seemingly not affecting execution. I did wonder if it was related to my app not updating issue.
