Description

If you install Ninja Form addon, there are PHP warnings in PHP 8.2 Deprecated: Creation of dynamic property WPSight_Framework::$ninja_forms is deprecated in wp-content\plugins\wpcasa-ninja-forms\wpcasa-ninja-forms.php on line 85

This warning causes new warnings like Warning: Cannot modify header information - headers already sent by (output started at \wp-content\plugins\wpcasa-ninja-forms\wpcasa-ninja-forms.php:85) in \includes\misc.php on line 1438

Fix

Everything was fixed just by adding new property to WPSight_Framework in wpcasa.php

public $ninja_forms;

I could sent PR but I am not sure if this is correct fix.
