For some reason ranks on my server quit showing up. I was using essentials and lordpermissions but for some reason ranks quit showing up as prefixes. I changed to essentialsx thinking it might help as it is updated regularly. I must have a wrong setting somewhere. I am wondering if you have any ideas. I am attaching my essentialsx config file in hopes that is where my error is. If you have any other ideas or need other info please let me know. I am on MC version 1.9.2 with Spigot and have essetnialsx chat jar.

Ranks aren't showing up how? You might need esschat for it to show up in chat. Or a permissions plugin for them to work.
