PermissionsEX Help + Some other stuff

Hi, I'm new to minecraft and craftbukkit. I played around with craftbukkit yesterday and it tried to PermissionEX and modifyworld. I followed the guide at permissionsEX wiki and made this permission.yml.

The prefixes does not show and one of the player can chat, break/build blocks etx while the other can't although I put them in the same group and deop both of them. Could it be due to the incompatibility of the version of bukkit I'm using, which is 1.7.9 or did I made a mistake with the yml file.

Also, I was just wondering how are the characters saved in the game? Are they saved in the .dat file with gibberish filename? Are we able to edit the players by accessing these files?

 

ssassassa9 Some of your prefix lines were indented too far. Fixed: http://pastebin.com/Y4DuV15a One other thing, make sure you have some sort of chat plugin on your server. Pex doesn't do the chat all by itself, so the only way to get the prefixes to show is for Pex to tell them to a chat plugin and then the chat plugin makes them work.

And yeah, the characters are saved in the gibberish.dat files. That gibberish is the new UUID system, which should make it so that even if someone changes their minecraft name in the future update, they will still keep all of their account information on your server.
