There could be a few things causing this. Here are some common fixes:
1- Make sure your platform is connected by going to
Connections > Platforms and press Add New Connections
2- Make sure you’re using an exclamation point or your global key before you enter a command. You can change your Global Key by going to
Commands > Global Settings > Global Key
3- Make sure Global State is on by going to
Commands > Global Settings > Global State
4- Check whether you have toggled any restrictions and disable them. You can do this by heading to
Commands > Global Settings > Restrictions and turn Restrictions off
5- Make sure your User Levels are selected for your commands
Commands > Edit your commands and make sure the commands have the correct User Levels set
7- Disable ‘Whispers only’ if it has been toggled
Commands > Global Settings > Whisper
