Warning in compatibility with php 7.2

Hello,

It seems that your plugin is not 100% compatible with php latest version 7.2.

There is a warning as you can see below :

FILE: /wp-content/plugins/autoptimize/classes/external/php/jsmin.php
—————————————————————————————-
FOUND 0 ERRORS AND 1 WARNING AFFECTING 1 LINE
—————————————————————————————-
109 | WARNING | INI directive ‘mbstring.func_overload’ is deprecated since PHP 7.2
—————————————————————————————-

Could you fix that?

Thanks

Florian
