CVar synchronizeConfig

Instructs the client whether to save character- and account-scoped CVars to the server for synchronization after each session, for recall on another machine or if config-cache.wtf is deleted. This setting has normal (client-wide) scope.

Settings

 * 1 - Default : CVar changes written to server
 * 0 : CVar changes only set locally

Details

 * Deleting the WTF folder while the client is turned off will restore all character- and account-scoped CVars to their last-synchronized value from the server as will default back to 1

Examples
Disable synchronizing from the chat window /console synchronizeConfig 0

Alternatively, exit WoW and insert the following line to Config.wtf: SET synchronizeConfig 0
