Essential permissions aren't working

Hey so I just made a free server on Atermos and none of the permissions from essentials are working. Like everything else works BUT essential permissions. Also, the commands only work if you're opped and they have no problem then.

I'm using PowerRanks for ranks and it's never had this problem before.

Here's my rank config for PowerRanks:

Code:

Default: Guest

  Guest:
    permissions: essentials.warp.spawn
                 essentials.build
                 essentials.warp
                 essentials.warp.list
                 modifyworld.*
                 essentials.warp.*
