Open Source Document Management System | OpenKM

I downloaded free openkm 5.1 from OPENKM site and installed it in my system. As of now it is running properly. But Iam encountering some problems:

1.->unable to save users list that I created. As long as jboss server is opened I can view user list but when Iam closing jboss and relogin into openkm I didn't find any user.

2.->No language preferences apart from english and espanol. Please send me how can I configure different languages into my tool.

3.->I didn't find any FORUM support option in my tool either in dashboard view or desktop view

4.->I couldn't find the CRYPTOGRAPHY option in my installed tool that is shown in the online demo.
