I'm on Step 2 of the Grocery List tutorial where I'm supposed to click Properties on Grocery List Backend, but the Output window (in Chrome) just keeps showing:
[2015-08-01 13:07:43.514] Error: Script error. (URL: /appbuilder/webclient/, LineNumber: 0:0)
It fails in different browsers as well. In IE it shows:
[2015-08-01 13:14:35.775] Error: Script error (URL: https://c15054651.ssl.cf2.rackcdn.com/live/webclient/2015.2.728.2/bootstrap.js, LineNumber: 0:0)
Ideas?
