When i type /plugins on my server, it has chat manager red. Do i need this for permissionsex? because it doesn't come up with the permissions and prefix's in game so i need a little help. If anyone that has teamviewer can help me out that would be AMAZING!
This is incorrect. Virtually any chatmanager will work with PEX, you don't have to use chatmanager that comes with PEX.
Chatmanager, the one that comes with PEX, is actually pretty limited in it's abilities, but for many servers, it's perfectly adequate.
