 * Not quite sure exactly how much you’d be able to handle this, but we’re seeing
   this error crop up on a client site:
 *     ```wp-block-code
       PHP Fatal error:  Uncaught TypeError: array_flip(): Argument #1 ($array) must be of type array, null given in /wp-content/plugins/ninja-tables/vendor/wpfluent/framework/src/WPFluent/Foundation/Application.php:51
       ```
   
 * WordPress 6.2.2
   PHP 8.0.29
 * Anything else I can provide as well if it’d help.

 * Hello [@tw2113](https://wordpress.org/support/users/tw2113/),
 * I have just tested the plugin with the latest version of WordPress with PHP 8.0,
   it worked without any issue. I am not sure why you are having such an issue. 
   To avoid this, I suggest you to roll back to PHP 7.4 to run the plugin without
   any issue. But if you want to stick with this(8.0) version, then it needs to 
   be investigated from your website dashboard and you need to contact our support
   for this.
 * Thank you
