Hello. Sorry, it looks like I missed the notification about your reply.
Based on your messages and the response in the screenshot, it seems the permission 'vip1' doesn't exist. Permissions are usually registered by plugins, which plugin created the 'vip1' permission?
Example of a correct command:
tperm grant group *groupName* *permName* wipe - Console and chat(/tperm)
tperm grant group *groupName* *permName* 3600 - Console and chat(/tperm)
tperm grant group *groupName* *permName* "2025-07-15 17:57" - Console and chat(/tperm)
o.grant group *groupName* *permName* wipe - Only console, for carbon "c." or "carbon."
o.grant group *groupName* *permName* 3600 - Only console, for carbon "c." or "carbon."
o.grant group *groupName* *permName* "2025-07-15 17:57" - Only console, for carbon "c." or "carbon."
