Warning: Parameter 1 to DJClassifiedsRegion...... Error Message

Hi,

Whenever i click on anything to do with the map or location names I get the following error message and wondered if you knew what causes it

Warning: Parameter 1 to DJClassifiedsRegion::getListSubreg() expected to be a reference, value given in /home/jobsandclass/www/www/libraries/src/Cache/Controller/CallbackController.php on line 173


Thanks,

Andrew
