Enfold Instagram Widget not Working

I tried to add the new code to: class-framework-widgets.php (framework/php/class-framework-widgets.php) but I get this error:

Your PHP code changes were rolled back due to an error on line 3038 of file wp-content/themes/enfold/framework/php/class-framework-widgets.php. Please fix and try saving again.
