Hey Blightsoul, if doing it via the chat commands isn’t working you can also try via the general config.
Please note, before doing this you will need to disable your addons as one of them could be the route cause.
- Hover the mouse over the chat window until the “General” tab shows up.
- Right click the general tab and click “Settings”.
- Click Chat Defaults on the bottom left.
- Click “Global Channels” on the left navigation bar
- Enable the channels at the top via the tick box, or join them from the available channels in the lower section
