PHP fatal error

Hi,

I was troubleshooting another problem so I turned on the WP debug and noticed that Elementor was giving a PHP fatal error on my setup.

[18-Nov-2018 20:33:17 UTC] PHP Fatal error: Call to a member function get_component() on null in ****/wp-content/plugins/elementor/modules/page-templates/module.php on line 345

Any ideas what this is about?
The PHP and MySQL are outdated on my clients server and I’m trying to move them to a new server.

Here is my setup information.
