That's a bug of JForum that occurs when using Jetty. It is already fixed in the development version. If you dont' want to wait for the next release, you can download the fixed class and recompile it by hand. The file is

I am using 2.1.4 so I checked out version 1.18.2 but I still got same error and at last it is fixed by

changing

(superRequest.getQueryString() == null)

to

(superRequest.getQueryString() == null||superRequest.getQueryString().length()==0)

Thanks a lot
