Beberapa komoponen diantaranya Zoom Gallery versi 2.5.1 RC2 buatan Mike de Boer pada Joomla 1.0.12 pada beberapa kasus di server hosting, jika kita akan melakukan seting, akan dijumpai pesan seperti dibawah berikut ini:
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 /[root joomla]components/com_zoom/www/admin/catsmgr.php on line 234.
