Warning: Call-time pass-by-reference has been deprecated - elatedcontent.module on line 189

Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. However, future versions may not support this any longer. in /home/xcomkids/public_html/sites/all/modules/contributions/relatedcontent/relatedcontent.module on line 189

Solution:
change:
_relatedcontent_menu_relatedcontent(&$items);
to:
_relatedcontent_menu_relatedcontent($items);
