When typing chat with a prefix, the prefix types in chat twice.

This is the config
groups:
default:
options:
default: true
prefix: "&8[Default]&f "
permissions:
- modifyworld.*

When typing in chat, it says:

[default] [Default] {PlayerName}

So it says the group, prefix and name.

This is a usually matter of the Essentials\config.yml file being configured (around line 530) to show the group, diplayname, and message. The displayname variable is prefix+username+suffix resulting in 2 group names showing.

Ok, it seems to still not work.

Here is the Essentials config.

I'm not sure what in these 3 files needs to be changed.

I'm home now and have access to my Pastebin links. :D

This should help clear things up:

Great. It seems to work.

Excellent. :-)

Feel free to come back if you run into any other issues you think are related to PermissionsEx. :-)
