Advanced File Manager Shortcode critical error

Follow up:

To make the plugin work, i had to edit the PHP file named file-manager-advanced-shortcodes.php and completely delete the function i’ll past here:

public function fma_shortcode_updates()
	   {
		    $path = $_SERVER['REQUEST_URI'];
			$file = basename($path, ".php");
			$file_name = explode('?', $file);
			if(($file_name[0] == 'plugins.php') || ($file_name[0] == 'plugins')) {
		    require_once ( 'upgrade/upgrade.php');
			$fma_plugin_current_version = $this->ver;
			$fma_plugin_remote_path = 'https://advancedfilemanager.com/upgrade/';
			$fma_plugin_slug = plugin_basename( __FILE__ );
			$fma_license_order = '1';
			$fma_license_key = 'success';
		      new file_manager_advanced_shortcode_updates( $fma_plugin_current_version, $fma_plugin_remote_path, $fma_plugin_slug, $fma_license_order, $fma_license_key );
			}

After completely deleting the content of the function and leaving it an empty one, the plugin started working completely.

Please, fix the issue of the updater! Thank you

Thank you, but how can i update to the next version if the update function is the one causing the critical error?
