Deprecated with PHP 8.2

[aryansann]

Choosing Merlin WP to work on my domain with PHP 8.2 gives me an error for a few files in merlin-class.php as deprecated. Can you help me on this while it works smoothly on 8.1

There are a bunch of undeclared variables which need to be fixed. Add this to the top of that class with the other declarations.

    /**
     * missing declarations
     */
    protected $ready_big_button_url = null;
    protected $slug = null;
    protected $hook_suffix = null;
