tabcompleter.groups.GROUPNAMEpermission. The plugin will look for your permission plugin's group instead. You do not need to give groups this permission anymore. You can safely remove it. You group names in the config must match your permission plugin's group names. For example, if your permission plugin has a group called
admin, then you must set the name in the config to use
/help, you must add it to all groups in the config.
