Drupal 7 version no longer works. Google client library does not work.

I tired all google client libraries upto 1.18 client library and it did not work for the Drupal 7 version of Droogle.

A WSOD and the error above:
Unable to refresh token: Error refreshing the OAuth2 token, message: '{#012 "error" : "invalid_client",#012 "error_description" : "The OAuth client was not found."#012}'

The site should not be WSOD if the token cannot be refreshed or an auth token not created correctly.
