    I have this warning: “Should be only variables passed by reference in” which the online search results in: public_html / remedionaturales.com / wp-content / themes / point / functions.php on line 369
    Now there I have this I do not know where to put my hand:
     

    add_filter ('get_comments_number' 'mts_comment_count', 0);
mts_comment_count function ($ count) {
     if (! is_admin ()) {
         global $ id;
       (line 369) $ comments_by_type = & separate_comments (get_comments ('status = approve & post_id =', $ id));
         return count ($ comments_by_type ['comment']);
     } Else {
         return $ count;
     }
}

    Anyone can tell me how to solve this? I get this message right in the pages of entries.

    Thank you.

    Have you made any to the theme at all?

    I want to say part of it could be this particular line:


    $comments_by_type = &separate_comments(get_comments('status=approve&post_id=' . $id));

    Part of that is because it is fairly old PHP code being used:

    As of PHP 5.3.0, you will get a warning saying that “call-time pass-by-reference” is deprecated when you use & in foo(&$a);. And as of PHP 5.4.0, call-time pass-by-reference was removed, so using it will raise a fatal error.

    If you haven’t already, try contacting the theme’s author about it.
