Hello. I'm just going to show this in pictures. When we are in a world, it shows the world name. So.. I turned it off in the config. It worked after I did the reload. But.. When I added me to the group Owner, never put a name down.... By my name tag. Any. This is with group manger and I turned of the world tag with Multiverse.
You have to add prefixes to groups that you wish to have a chat prefix. /mangaddv prefix <groupname> <prefix> Take for example /mangaddv prefix Owner (Owner) Which will make your name appear in chat as < (Owner)RazorHawk361> Based off of the pictures above, that's how it should look for the most part. You can add colors too. Also, Multiverse world prefixes don't affect Groupmanager group prefixes.
