Hello, all,

All-day my entire league receives an "Invalid signature" error message upon game start. Game room is not even loading, so I presume the crap is from your side.

Yes, we did clear the caches, restarted browsers, reinstalled browsers. Nothing works.

The error message in console states:

Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘https://www.facebook.com’) does not match the recipient window’s origin (‘https://apps.facebook.com’). stormfall
