[SOLVED] configure the server for leaderboard

btw. server console tell me this:

Code:

^7[20125104/10/12_1451:07]Downloading http://www.xonotic.org/weaponbalance/ -> memory
^7[20125104/10/12_1451:07]Downloading http://stats.xonotic.org/stats/submit -> memory
^7[20125104/10/12_1451:07]Got response from weapon stats server:
^7[20125104/10/12_1451:07]  OK
^7[20125104/10/12_1451:07]End of response.
^7[20125104/10/12_1451:07]Weapon stats written
^7[20125104/10/12_1451:08]Player stats writing failed: -500

Found this: http://dev.xonotic.org/issues/804 maybe the same problem? - But key_0.d0si or key_0.d0si.duel (for duel serever) is in directory ...
And if it is what to do?
