Freemarker errors are often the result of an error that occured earlier and was not reported to the browser. Check your app server logs for more error details and post back here.

One thing to check is that you don't have any partially deleted forums in the database (or maybe in memory). The reported error is based on trying to get the last post of a specific forum. The null pointer is most likely due to the forum object being returned as null.
