Here is my permissions file:
http://pastebin.com/DbvFBQx6

This is the error that concerns me:
30.01 18:08:33 [Server] SEVERE Permission node 'groups' in server config is invalid

 

you have old pex plugin update it

try it

http://pastebin.com/7VucRCXM

and always users 1st than groups

 

Is there a special reason?
According to my experience it does not matter what comes first.

 

PermissionEx 1.18 is the latest release from what i can find.

 

My server dont have premissons and works like i have =0

 

[Server] INFO Your Version of PEX is out of date. Please update.

I have updated PermissionsEx to version 1.18 which is the latest. Why is it telling me its out of date?

 

fak0r with some plugins it can make error or dont work

if i remember good with mcmmo for sure but i dont know how it goes with other plugins well better to keep it this way
