Errors triggered by plugin

Hello,

I have been seeing a lot of errors with the following stack trace – Google bot is not able to fetch pages and is showing a 500 error (fetch as google works for the same page when CF7 is deactivated). Any idea how I can fix this?

2016/09/18 07:39:46 [error] 10027#10027: *390304 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Uncaught Error: Call to a member function get_queried_object_id() on null in /var/www/goheritagerun/wp-includes/query.php:61
