Excuse me, I am reposting from the old newsgroup to this one....

The particular error appears to be:
[Tue Jan 10 13:50:48 2006] chart.cgi: Use of uninitialized value in
numeric gt (>) at Bugzilla/Chart.pm line 223.
[Tue Jan 10 13:50:48 2006] chart.cgi: Use of uninitialized value in
numeric lt (<) at Bugzilla/Chart.pm line 232.

it because we're using Groups? It presents the page each time and the
chart is missing. We've enabled data sets generation, and this seems to
have made the Old Charts work.
