CVar taintLog

Enables logging of UI taint messages to. Like all logs in WoW, this file is written periodically and once at logout.

Default setting

 * 0 :Taint logging is disabled by default

Possible settings

 * 0 :Disables taint logging.
 * 1 :Enables basic taint logging. This is probably enough information to track down a problem.
 * 2 :Enables full taint logging. Use this if basic logging doesn't give enough information. The log will grow rapidly in size with this option.

Changing this setting
In-game, type the following /console taintLog setting

Alternatively, you can exit wow, open the Config.wtf file, and add the following line: SET taintLog setting
