Graphs missing titles and data points

I am running three different Hobbit servers at three different sites and all work great except one. On the one not running great, I see everything fine except that all graphs are missing titles and lables along grid lines. Other than this missing text on the graphs, the graphs show the data fine. For the life of me I cannot figure out the difference between this misbehaving installation of Hobbit and the other two that are working great. Could anyone offer any hints as to where to look?

Thanks in advance for any help,
