Earlier today, we have released version 2.4.0 of the Openfire Monitoring Service plugin. This plugin adds both statistics, as well as message archiving functionality to Openfire.
In this release, compatibility with future versions of Openfire is added. A bug that affects MSSQL users has been fixed, and the dreaded “Unable to save XML properties” error message has been resolved. A few other minor tweaks have been added.
As always, your instance of Openfire should automatically display the availability of the update. Alternatively, you can download the new release of the plugin at the Monitoring plugin’s archive page.
Is the plugin loaded? It is likely that the cause of the problem is logged when the plugin is attempting to start. Please reload the plugin in Openfire, and see if anything is added to the log files while you’re doing that.
I checked in the log that the plugin was not able to start even when reinstalling… I deleted the plugin folder on the server and reinstalled it via the portal. It worked perfectly again.
