I'm using your plugin in 40+ of my clients sites. This morning, I started getting emails from al my clients stating that their analytics data is no longer available.
I logged into all sites and I'm getting this message:
Error gathering analytics data from Google: usageLimitsuserRateLimitExceededUnregUser Rate Limit Exceeded. Please sign uphttps://code.google.com/apis/console
I have created a project for one of the websites with this problem inside the google api console, but there is no place in Google Analytics Dashboard to put the API Keys.
How should I fix this issue?
