Fatal error

Hello, do you have any ideas why we get this error in our php logs? The contact form correctly sends the message though and it appears just like once or twice in a day or two.

Fatal error: Uncaught Error: Call to a member function get_status() on null in /home/xxx/public_html/wp-content/plugins/contact-form-7/includes/contact-form.php:734
