I have been trying to run a Minecraft server with PermissionsEx, but it hasn't been working quite right. The server does not even seem to acknowledge that the permissions file is there or has been changed. I believe I am able to change individual players' settings through PEX commands, like adding name prefixes, so the plugin itself is working. I don't know what the problem is with the permissions.yml file, so here you go.
You could try using the command /pex reload or just restarting your server. That should normally do the trick. Hope this helps, - Mark
Nonnel They might not be using the latest PermissionsEx. MeLikeChoco You need to put empty quotation marks or remove the empty suffix lines. Code: suffix: If you can, paste your permissions file on pastebin.com amd share the link.
Nonnel On top of your permissions.yml, you forgot a colon after "Default". Change this: Code: groups: Default [...] to this: Code: groups: Default: [...]
