 * When I enable debug mode in wp-config.php, I’m getting this message:

 * UPDATE: I have reversed PHP 7.3 to PHP 7.0 and the first 2 errors have gone away.
   
   So now I’m guessing Revolution Slider does not support PHP 7.3?

 * I personally would be very concerned about that first deprecated message. `create_function()`
   has many issues, and as of PHP 5.3 (released 10 years ago!), [a vastly superior replacement](https://www.php.net/manual/en/functions.anonymous.php)
   is available.
 * Hopefully there is a newer version of Revslider that uses more modern (and more
   secure) coding.
