If you've configured mod_GoogPlus Feed but the feed doesn't appear, perform the following steps to help narrow down the cause.
- Set Joomla's Error Reporting to
Development
- Access the page displaying the module
If you see something similar to the following
file(https://www.googleapis.com/plus/v1/people/nnn/activities/public?alt=json&maxResults=20&key=yourkey):
failed to open stream: HTTP request failed! HTTP/1.0 403 Forbidden in
It means that Google's API is refusing your request. To gain an understanding of why, SSH onto your server and do the following (replace $URL with the URL displayed in the error message)
curl -v "$URL"
The output should include some JSON detailing why the request was refused. Access your Google API console and correct the root cause.

(Correct at time of writing, but Google seem to like changing the interface quite regularly)

Take the generated key and use that.
Making sure the Google+ API is enabled
