I am working on a fun plugin where i want to be able to add strings(permissions) to a list but the command doesnt seem to fire.

I kinda need this plugin finished asap so any help would be appreciated

BasePlayer player, Configuration config

Thet isn't a valid signature for a command method.

BasePlayer/IPlayer, string command, string[] args

Should I use that (I had this previously). it gives me the error that it cannot find the object reference.

I'd need to see what you are using, but I suspect that isn't the cause of your NRE.

Shall I show you the error?

Failed to call hook 'DebugBlessed' on plugin 'FactionsPlus v0.0.1' (NullReferenceException: Object reference not set to an instance of an object) at Oxide.Plugins.FactionsPlus.DebugBlessed (BasePlayer player, System.String command, System.String[] args) [0x0002c] in <461e00cabecd4e2e9f73d85d4424d96f>:0 at Oxide.Plugins.FactionsPlus.DirectCallHook (System.String name, System.Object& ret, System.Object[] args) [0x0016e] in <461e00cabecd4e2e9f73d85d4424d96f>:0 at Oxide.Plugins.CSharpPlugin.InvokeMethod (Oxide.Core.Plugins.HookMethod method, System.Object[] args) [0x00079] in <80b90e8213db44b29ec2d4111764172c>:0 at Oxide.Core.Plugins.CSPlugin.OnCallHook (System.String name, System.Object[] args) [0x000d8] in :0 at Oxide.Core.Plugins.Plugin.CallHook (System.String hook, System.Object[] args) [0x00060] in :0

They error would mean something in that method is null, not an error with the signature. You'd need to add some debug output to see what may be null, but right now it is looking like something with your configuration.

My config does say null. I tried to add a string but it didnt allow it apperantly

I can't see your image.

{
  "Permissions : The list of permissions that will be granted at to the blessed team.": null
}

Have you tried deleting the file and allowing it to be re-created? LoadDefaultConfig is only ever called once, so if you didn't create default data originally, then it would be null and not updated automatically.

I have indeed tried to remove it multiple times giving the same output.

Save the config after it loads the default config in put somthing there to verify its called..

LoadDefaultConfig()​
