Nostalrius Begins - Quality wow vanilla realm (1.12)

Some time ago (10-7 days maybe?) I installed an Diablo 3 like UI. Once I did that it put my chat type box above the chat and made it so when I resize the chatbox type box does not resize. I reinstalled WoW and created a new charachter, it is still there. I don't understand what is going on .

Try deleting the "chat-cache.txt" file in your World of Warcraft Class\WTF\Account\%account name%\Nostalrius Begins\%character name% folder. The file should recreate next time you launch WoW, login, logout, and close and reset chat settings to default values.

If that doesn't work, try deleting your entire WTF folder in the WoW Classic folder. Same thing: it'll recreate with default values next time you login/out and close WoW. You'll lose any custom addon, macro, and UI settings, but it clears the entire cache of your account settings including chat and UI stuff.
