Apache::OpenIndex question

[Noam Solomon]

Hi,
    Anyone know what might be going on in this error message?

[Tue Mar 12 12:03:59 2002] [error] [client 192.168.1.25]
Apache::OpenIndex internal error: NULL command
[Tue Mar 12 12:03:59 2002] [error] Can't use an undefined value as an
ARRAY reference at
/usr/lib/perl5/site_perl/5.6.0/i386-linux/Apache/OpenIndex.pm line 566.

Here are lines 564-566...

sub plain_page {
 my ($r,$args,$dirhandle,$mode,$isroot)=@_;
 my $cfg = Apache::ModuleConfig->get($r);
 my $ignore_regex = join('$|^',@{$cfg->{ignore}});

Thanks,
Noam Solomon
