This is the error I get on the webpage when I click on stats in OTRS

Can't locate object method "GetObjectName" via package "Kernel::System::Stats::Static::StateAction" at /opt/otrs//Kernel/System/Stats.pm line 2234

System configuration:

OTRS 2.4.2 – running mod-perl 2, .set permissions run , all modules accounted after running  ./otrs.CheckModules

Cent OS 5.2

Apache 2

SQL Server 2005 – (Network packets set to 20 megs)

Any help would be greatly appreciated

Thanks,

Rob
