[Lookup for group channel not available]

Hi,

The chat channel Lookup for group is not available when a player isn't in a city. I tried to modify the worldserver.conf file with:
#
#    Channel.RestrictedLfg
#        Description: Restrict LookupForGroup channel to characters registered in the LFG tool.
#        Default:     1 - (Enabled, Allow join to channel only if registered in LFG)
#                     0 - (Disabled, Allow join to channel in any time)

Channel.RestrictedLfg = 0

I restarted the server but it didn't help.

Thanks
