Solved How to remove custom Tabs!

The other day I installed 1.8 tags on my server.

After I installed it this pesky little thing appeared:

I don't want the "U" or the colored tab! I uninstalled the plugin, made sure no files were left behind, and all that. However I still can't find what is making the tab menu look like that! It only appears there. In fact, I've disabled all plugins to see if that would fix the issue. But, nothing has helped. Any tips, tools, or advice on how to get rid of "U"? I've run out of ideas!

 

@AryaRaiin
1) Have you restarted your server/client?
2) Please list all plugins.

 

@AryaRaiin
1) Remove scoreboard.dat in your worlds.
2) Use a plugin that doesn't mess with the scoreboard. Haven't tested it, but worth a try: http://www.spigotmc.org/resources/itag.342/. It mocks TagAPI, so you have to use a TagAPI plugin with that.
If even the latter colors tabs, then it might be because of the changes in 1.8 with the nameplates, which means you will have to deal with the scoreboard anyway.

 

Thank you so much! I deleted the scoreboard file and it worked. I'll look into that plug in as well! ^.^
