I have updated the mod to its latest version in minecraft 1.18.2 - I have updated Creative Core as well and I have the following problem:

The /cam command by itself works fine, the problem comes when I try to use the /cam-server command. It just doesn't recognize it and gives me the following message: Unknown command.

My server is Magma and I had no problems in previous versions until I upgraded to 1.18.2.
I don't know if it requires some special permission or it's a bug in the mod.

And CMDCam is installed on server side?

That's right, it is installed on the server and on the clients.
The strange thing is that in the console does not mark any error, simply the command only sends the message of: Unknown command

Can you send me the log file of the server?

I will close this issue due to inactivity. If the issue persists just post the log file here.
