Plugin Help /PEX not working at all

I don't know where I went wrong it might just be a simple noob mistake, but somehow I have changed something and no matter whether I type /PEX in chat or PEX on my server console it does not give me any sort of response. I used to have prefixes next to my name but now there is none, for the record I will supply you with a copy of my permissions.yml

try using

Code:

groups:
  default:
    permissions:
    - modifyworld.*
    options:
      prefix: '&7[Lid]&7 '
      default: true

or pastebin.com so all spaces are still there

 

Might be helpful, find a YAML checker online or something and see if your groups have any unwanted spaces or anything. Also did you use the in-game commands or type it yourself?
Heads up, YAML files don't like when you use TAB. (I may be wrong)

 

I use this to check all of my config files and permissions to make sure I didn't mess something up

did you /reload
That will break pex until the server is started cleanly, if there are no errors in pex otherwise...

 

never use /reload to reload something if u dont wanna restart least use /pex reload, i never had pex break from that and use it often, however some perm nodes are just messy all together.. infact...i cant reload my server via /reload without it crashing. X) so /pex reload is kinda forced.
