Problem/Bug Normal Players can't use /warp

Hi.
I have a problem. I've been setting up a Bukkit Server for the past 4 days and now I have encountered a huge problem:
The group 'Spieler' (means 'Player' in German) can't use /warp. Also Architects, VIPs and Moderators can't use it. I've set the Per Warp permission to true and I also have tried pretty much every permission code there could be.
I've tried
essentials.warp
essentials.warp.*
essentials.warps
essentials.warps.*
essentials.warp.<warpname>
essentials.warps.<warpname>

Please help.

Edit: The Server is on 1.7.10 by the way
Edit2: I'm using PermissionsEx

 

The only 3 permissions you need:
essentials.warp
essentials.warp.list
essentials.warps.<warpname>

 

To make sure I understood it: I put the name of the warp for <warpname>, do I?

 

@TayroTR Of course

 

Doesn't work.

 

Do they have essentials.build already? If not, add that. @TayroTR

 

Still doesn't work.

 

@TayroTR I think it has to do with the Permission Plugin you're using
I had the same issue, now im running my server without any Permission Plugin and everything works fine with warps

 

What? How can? Huh? I don't get anyth... WHAT? How should you run a server without permissions plugin? That's like putting a flower on your table without a flower pot. It doesn't work. There can't be any groups without a Permissions Plugin.
By the way: I switched from Pex to GroupManager.
Here is my groups.yml:
