Body: <p>I just updated to 3.1 and I'm getting the php error:</p>
  
  <p>PHP Notice – yii\base\ErrorException</p>
  
  <p>Undefined index: settings</p>
  
  <p>It probably has to do with the Cheat Sheet plugin.  I deleted that folder in the vendor directly but no luck.</p>
  
  <p>I can send along the link showing the errors.</p>

Title: Getting PHP Error on upgrade from 3.0.36 to 3.1
ThreadText: # Getting PHP Error on upgrade from 3.0.36 to 3.1
  
  (Asked by: username_0 on 2019-01-15)
  
  I just updated to 3.1 and I'm getting the php error:
  
  PHP Notice – yii\base\ErrorException
  
  Undefined index: settings
  
  It probably has to do with the Cheat Sheet plugin. I deleted that folder in the vendor directly but no luck.
  
  I can send along the link showing the errors.
  
  Thank you!
