Resetting Channel Settings

[eXeel]

Back in the days on my Priest, I played around with colours on General and Guild chat, and some mods that added new channels to auto join.
But now it is annoying with those extra channels that somehow pushes my General channel to /9 and my Trade to /1 etc.

How do I completely reset that chars channel settings, colours, autojoins, channel numbers etc?
What foldes to delete or what commando to type? Need help a lot, as I started playing it again in raids...

Thanks.

Enter your WOW install directory, and from there go the following path:

<wow install> \ WTF \ Account \ <account name> \ <server name> \ <character name>

From there you should see the following files:

chat-cache.txt (control channels)
chat-layout.txt (control color and chat-box placement)

These two files detirmine your chat-setup. If you delete them you should regain the default settings.
Alternately you can copy them to another character folder to make that characters chat look just the same.
