I have a classic OTRS Windows installation.

In the Apache Log file there are the following errors:

[Wed May 19 10:56:45 2010] [error] [client 10.229.44.36] Use of uninitialized value $_ in -d at C:/PROGRA~1/OTRS/StrawberryPerl/perl/lib/CGI.pm line 4083.

And also in otrs.log there are this message:

Wed May 19 11:09:59 2010][Error][Kernel::System::DB::Connect][228] Unknown system variable 'DATEFORMAT', SQL: 'SET DATEFORMAT ymd'

What does it mean?

Thanks
