 * Hi. I got a fatal error using PHP8.
 * According to your description in other people’s replies, I have changed the file
   name bootstrap80.php.sample => bootstrap80.php
 * This problem is solved, but there is another problem:
 * Uncaught Error: Undefined constant “AppBuilder\AUTH_KEY” in /Users/xxxxxx/Local
   Sites/xxxx/app/public/wp-content/plugins/app-builder/includes/Setting.php on 
   line 25
 * (replace my privacy with xxx, does not affect reading)
 * How can this be resolved? Thanks!

 * Solved. Site Tools does not generate keys automatically. After adding it manually,
   everything works fine.
