Redmine

Hi.

I have an issue with the Gantt PNG export, where it shows error when I'm trying to produce a PNG.

The page says: The image “http://192.168.253.31:88/redmine/projects/ncit/issues/gantt?format=png&month=6&months=20&year=2009&zoom=4” cannot be displayed, because it contains errors.

When I'm looking through the logs, I see the error below. Any idea what it means?

Thanks in advance!
