WTFBBQ is going on?

Thanks in advance.

From our knowledge base:

The Openfire admin screen show an empty screen on http://jabber:9090/plugins/monitoring/stats-dashboard.jsp

Root cause

The table ofRRDs has incorrect data that causes the JSP to crash. The error log may have an entry like this

Resolution
