Please post your config.yml. This sounds like you have TabListDisabled set to true, or are using server/client version < 1.8.3

i am useing 1.7.10 bukkit server and my config is:

Are you receiving any errors in the console? Are you using a database or flatfile?

Edit: Try this version for me please http://ci.playmc.cc/job/NametagEdit/27/

Tested on 1.7.10.
Used his config.
Flatfile or database doesn't matter.
Tabs work fine.
