[API Error] Unexpected token in JSON

Scripts are disabled due to error. Error message:  Error setting up API settings: SyntaxError: Unexpected token in JSON at position 158 Game has a custom made character sheet with html and css. Only non-disabled script is this in its entirety (error goes away if I disable this last script): log("hello"); All browser extensions disabled Chrome browser Ubuntu Cache and cookies cleared JavaScript enabled

Just to confirm, if you switch to a non-custom character sheet, the problem goes away? Is this on the Dev server, or the Production environment?

I've just tried switching to "None" character sheet, and the error is still there. Production environment. My other game on there, with extensive scripts (never assigned a character sheet) works fine though...

Do you have anything important configured in the API of that game?  You could try resetting your state variable to see if the issue is in it. WARNING: This will destroy any settings stored in state, Use at your own risk! state={};

That cleared it up! Thanks! Wierd, I never set anything on the state variable.

Some script may have.  Glad that fixed it for you!
