WordPress for Google Docs Error

Just installed it and when I go to OPEN it, It shows up on the right and there is a button there to Add WordPress Sites but there is an error at the bottom saying Error: Authorization is required to perform that action.

Please report this error

So.. I am. I cannot do anything else it seems with the addon.

Reproduce the error by opening the WordPress for Google Docs add-on and selecting Add WordPress Sites. Start by tracing the authorization flow for that action; done means the add-on opens the site-selection flow without showing the authorization-required error.
