PHP Core Warning – yii\base\ErrorException Module 'newrelic' already loaded craft 3 I upgraded Craft 2 to Craft 3.3. Sometimes I am getting an error in admin like below when saving entries or taking some URL.


  PHP Core Warning – yii\base\ErrorException Module 'newrelic' already loaded craft 3


Please help.
Not really related to Craft or the update from Craft 2 to 3.  You'll probably want to contact your hosting provider.  It sounds like there are multiple attempts at loading the newrelic module in your php.ini file.
