    I ran a compatibility check by [https://wordpress.org/plugins/php-compatibility-checker/](https://wordpress.org/plugins/php-compatibility-checker/)
   before I would upgrade from PHP 7.2.30 to 7.3.
 * There are 6 warnings and 1 error for Autoptimize.

 * Shall I proceed with upgrade to PHP 7.3?
