Hi I have a fresh install of openfire on a linux x64 box, on which the monitoring/statistics graphs are not being loaded. Looking at the logs, I keep seeing the following error:

I’ve searched around and nothing seems to address this issue, and the most frequent response (try to uninstall & re-install the plugin) has yet to produce any different output. Any help would be appreciated.
