in your server config u have to load the weapon config!
u can add all settings there or say what file he should load
in my fieles

set xp_config "conf/<gametype>settings.cfg"
but normaly he should use the default.cfg when no weapon cfg is load!

read here http://excessiveplus.net/docs/config.html

Excessive Plus is very customizable. You can create your very own personal settings, change the weapon behaviour, the gameplay, items, nearly everything to fit your needs.

You can also use the pre-made configurations inside the "conf/" directory.

To load these configurations use
/load <conf/yourconfig.cfg>

// or if you are admin of a remote server

/rcon load <conf/yourconfig.cfg>

good good good
