 * When attempting to edit a page using Elementor, the side panel never completes
   loading, remaining greyed out with a loading wheel.
 * Checking the console, I’m seeing a 500 response from admin-ajax.php
 *     ```wp-block-code
       POST https://[SITE_NAME_HERE]/wp-admin/admin-ajax.php 500 (Internal Server Error)
       ```
   
 * Finally, my WordPress debug.log contains the following error message:
 *     ```wp-block-code
       PHP Fatal error:  Uncaught Error: Call to undefined function ThePackKitExtensions\Elementor\wp_json_decode() in /home4/wiscoob1/public_html/wp-content/plugins/the-pack-addon/includes/header-footer/includes/extensions/elementor/module.php:69Stack trace:#0 /home4/wiscoob1/public_html/wp-includes/class-wp-hook.php(324): ThePackKitExtensions\Elementor\Module->register_ajax_actions(Object(Elementor\Core\Common\Modules\Ajax\Module))#1 /home4/wiscoob1/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters('', Array)#2 /home4/wiscoob1/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array)#3 /home4/wiscoob1/public_html/wp-content/plugins/elementor/core/common/modules/ajax/module.php(154): do_action('elementor/ajax/...', Object(Elementor\Core\Common\Modules\Ajax\Module))#4 /home4/wiscoob1/public_html/wp-includes/class-wp-hook.php(324): Elementor\Core\Common\Modules\Ajax\Module->handle_ajax_request('')#5 /home4/wiscoob1/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters('', Array)#6 /home4/wiscoob1/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array)#7 /home4/wiscoob1/public_html/wp-admin/admin-ajax.php(192): do_action('wp_ajax_element...')#8 {main}  thrown in /home4/wiscoob1/public_html/wp-content/plugins/the-pack-addon/includes/header-footer/includes/extensions/elementor/module.php on line 69

 * I’ve confirmed that disabling the plugin fixes the 500 error.

 * Thank you very much for looking into this! It looks like I’m already on the latest
   version, 2.0.8.7, published 3 weeks ago. I’ve updated Elementor and Elementor
   Pro to v3.23.3, but the issue still remains.
