 * Hi
 * I am testing the php 8.0 environment right now
    wordpress 5.6.2 / php8.0.2 / 
   WP-Optimize 3.1.7
 * After changing from php7.4 to php8.0, “ReferenceError: Can’t find variable: loadAsync”
   error has occurred.
 * The error is the web browser’s console log.

 * If disable Minify, not occur problem
    WP-Optimize -> Minify -> turn off to “Enable
   Minify”
 * Even if the two options below are turned off, a problem occurs.
    Enable merging
   of CSS files and Enable merging of JavaScript files
 * Thanks

   Thanks for sharing this, I’ll report this to our development team to run some
   tests on PHP 8+
 * Hopefully this should get fixed in future release.
