Can’t use function return value in write context (PHP 7.2)

Hi,

I am trying to add your code:

add_action( ‘cf7_2_post_status_post’, ‘publish_new_post’,10,3);
/**
* Function to change the post status of saved/submitted posts.
* @param string $status the post status, default is ‘draft’.
* @param string $ckf7_key unique key to identify your form.
* @param array $submitted_data complete set of data submitted in the form as an array of field-name=>value pairs.
* @return string a valid post status (‘publish’|’draft’|’pending’|’trash’)
*/
function publish_new_post($status, $ckf7_key, $submitted_data){
/*The default behaviour is to save post to ‘draft’ status. If you wish to change this, you can use this filter and return a valid post status: ‘publish’|’draft’|’pending’|’trash’*/
return ‘publish’;
}

I am getting an error:
Can’t use function return value in write context
line 193, file: wp-content/plugins/post-my-contact-form-7/public/class-cf7-2-post-public.php

I noticed people had similar problems with PHP5*, I am using 7.2. Am I doing sth wrong?
