API KEY & API Shared Secret Key

I am getting this error after I enter the API Key and the API Shared Secret Key in the flickr module setup when saving info.

Warning: Call-time pass-by-reference has been deprecated; If you would like to pass it by reference, modify the declaration of system_settings_form_submit(). 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/content/g/r/e/greenroyd01/html/Greenroyd/modules/flickr/flickr.admin.inc on line 87

I am viewing this file through my ftp but im not for sure exactly what I am needing to do.
