Problems with the statistic page installation

RT Users

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!

What are Your versions of perl, gdlib, GD::Graph? Can You send me a
copy of the URL string that is falsely generated.

What are the names of Your queues?
