He instalado la extensión, pero despues de instalarlo me aparece esto :

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 C:\AppServ\www\joomla2\administrator\components\co m_joomfish\joomfish.class.php on line 1114

¿Sabes como puedo solucionarlo?
