Warning: Call-time pass-by-reference has been deprecated in version 5.x-1.x-dev

Hi,

I have installed the new version dated 18-May. All works fine except that I get the following warning on top on the page:

Warning: Call-time pass-by-reference has been deprecated; 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. in /home/iessanrosendo/departamentos/filosofia/modules/quiz/quiz.module on line 538 Warning: Call-time pass-by-reference has been deprecated; 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. in /home/iessanrosendo/departamentos/filosofia/modules/quiz/quiz.module on line 541

Well, I like so much the module that I can take it even with this nagging, but if possible, I would like to ride it off

Any suggestions?

Thanks in advance!!!
