Unfortunately, the plugin is not compatible with PHP 8.0 or newer. The reason is this line in the PHP file:

add_action( 'widgets_init', create_function('', 'return register_widget(“tawhidurrahmandearthirtyWidget”);') );?>

The PHP function create_function() no longer exists since PHP 8.0: https://www.php.net/manual/en/function.create-function.php

This has already caused the website to fail for other users. I would recommend updating this.
