Comment:

 @ispreview That will need a backtrace as this is likely caused by a plugin
 or theme doing something wrong. If not, we still need to know where in
 Core to fix the incorrect function call as the function in the
 `functions.php` file is passed incorrect information, which should be
 fixed at the point the information is passed, not where it is received
 (which is where the deprecation is being thrown).
