Asteirsk-gui shows only System Status anymore

I have installed certified-asterisk-1.8.11-cert8 and then asterisk-gui (GUI-version : SVN–r5219)

After a couple of restart it worked as expected.

I inform my partner to check it and he tells me he can only see System Status, no other menu points. First I thought it might be locked that two admins are logged in and logged out.

Now it is for each one only the System Status available anymore.

I use Ubuntu 12.04 on a cloud server. What am I missing?

I checked the permission of the /etc/Asterisk directory - all 644
