After upgrading cocos creator project from 1.6.1 to 2.2.2 I’m getting a black screen on the web preview and the simulator view is freezed.
During the web preview there is no error displayed on the chrome console.
This error is shown only in the developer tools when simulator view
“[Vue warn]: Attribute “id” is ignored on component because the component is a fragment instance: http://vuejs.org/guide/components.html#Fragment-Instance”
Help needed please
