[rt-users] Problems with the statistic page installation

[Schulz, Bjoern]

Hello!

I got big problems to install the statistic page. After installing, the
statistic
menue point appeared immediatly, but I don't get any graphics if I choose
one of the
statistic pages. For example if I try
TimeToResolve I got the following errors for the "Chart"-Url.
When I define the data array manually in Chart" it seems to work.

Bye!


System Suse8.2/Apache1.3.28/modperl1/RT3.06
