PHP 7.1 Warning

In wordpress root, where is wp-contents folder, PHP 7.1 gives a warning in error_log.

[06-Mar-2017 23:49:32 UTC] PHP Warning:  Parameter 2 to qtranxf_excludeUntranslatedPosts() expected to be a reference, value given in /home/[---]/public_html/wp-includes/class-wp-hook.php on line 298

It doesn’t throw warnings on PHP 5.6 or 7 .
Looks like it happens when switching languages, and there is/are some hidden untranslated post/posts.

Thanks,
