    This Notice is showing up in my debug.log.

    I check the value of $post and it is null.
    The page I was loading was the edit screen for a product.
    As far as I know this variable is only set if the loop is started.
    @see https://wordpress.stackexchange.com/questions/286241/global-post-shows-null-in-some-of-my-custom-post-types-archive-pages
    So I assume that this isn’t the case.

    I get rid by editing contact-form-7-dynamic-text-extension.php:329 – 332
    I change

    	global $post;
    	//echo '<pre>'; print_r($post); echo '</pre>';
    	$val = $post->$key;
    	return $val;

    to

    	global $post;
    	$val = '';
    	if($post instanceof WP_Post){
    	//echo '<pre>'; print_r($post); echo '</pre>';
    	$val = $post->$key;
    	}
    	return $val;

    Therefore $post is checked before accessing it and if it is not an instance of WP_Post then the function will return an empty string and will not cause a notice anymore.
