Question World Prefix Caused By permissions Ex?

I never had permissions ex before. I always had group manager, but group manager doesn't work for 1.8! So i had to switch to PEX! Now I get [world] [Group] [name] !!! I've went into my multiverse-core files and turned off the prefix thing, (it has always been). the prefix did not appear until PEX was added.

Also now, my factions don't show before the name... please help!

What prefixes do you want

 

Group Manager works with 1.8 , why not to you?

 

Thanks for trying to help! I was able to contact support at my server host and they helped me get the right plugins. I needed the essentials 1.8 snapshot from spigot Jenkins and also had to download essentials spawn. Then I had to go in the essentials folder and take #add prefix suffix - false To. Add prefix suffix - true. Then group manager worked! Thank you!
