Warning message regarding a plugin that has been deleted

Plugin: Status

I tested Status on multisite ProSites but decided against it and deactivated/deleted. I am now getting the following warning when someone processes a prosite transaction:

Warning: fopen(/home/usingess/public_html/wp-content/plugins/quick-status.php): failed to open stream: No such file or directory in /home/usingess/public_html/wp-includes/functions.php on line 4183
