When logged in with Administrator rights on Oracle WebCenter Content Server (formerly Oracle UCM which also was Stellent Content Server), a debug toolbar shows up on the bottom right corner. How can the Debug toolbar be enabled or disabled? Is there a configuration using which this can be controlled?
according to this link, you probably have the IsPageDebug=1 parameter in your URL.
If that is not the case the option is probably set in the config.cfg file in your server, here is the Oracle documentation about it.
Hope this help!
