I've compiled a new version here:

http://emac.dfbgaming.com/dFb_AccessControlG.zip

I've also removed code that has nothing to do with muting players (demos, player logging, multiple admins).

Like before you need to modify the command line and UTWebAdmin.ini but use:

?AccessControl=dFb_AccessControlG.dFb_AccessControl

and

QueryHandlers=dFb_WebControlG.dFb_WebAdmin

All player mutes will be written to the UTGame.ini file so you can copy your existing player mutes from UTdFb_AC.ini to UTGame.ini.

I've also included the source code in case you want to modify anything to your needs in the future.

If you want to continue to use the files I sent you earlier and see your bans from UTGame.ini, you need to copy the [Engine.AccessControl] section from UTGame.ini to UTdFb_AC.ini
