Connection Error/Problems (Old Widget That Was Previously Working)

Most likely Google expired your third party connection.   (Instagram, Twitter, Facebook, Linkedin, Google, etc do this to third party connections every 60 days or so -- there's no way to stop this, or a connection can be expired upon changing a password). 

The fix is simple!
Step 1: Reconfigure your existing Google+ widget by clicking on the gear icon located at the top right corner of the widget. 

Step 2: Click on the Google Account drop down and select the first empty entry in the list. Then click on the Add Account button located next to this drop down list.  

Step 3: A new popup will open where Google will ask you to confirm the connection. Click on the Accept button.  
Step 4: The popup will automatically close and you will be back on the widget configuration screen in Cyfe. Now click on the Save Widget button.
You should only have to do this for one widget.
