Robo-Tank v6.6 is Ready

...
If you have Chrome, right click on the page and click "inspect", a window will open in the browser. In that window there are tabs at the top, click the "console" tab. Then reload the page again, this time click and hold the refresh button and a drop down will appear. Then click "empty cache and hard reload". If it's still blank send me the info in the "console" you opened. That should tell me where it's getting stuck.

I just attempted an upgrade to V6.6 and get the black screen after login from both Chrome and Firefox.  Here's a screenshot of the console after the "empty cache and hard reload" operation.

   

Any help or ideas for getting this running again would be much appreciated!

Thanks,
Phil
