Use the cfsetting tag showDebugOutput attribute to turn off debugging output for a specific page. The attribute controls debugging output only if the Debugging Settings page in the ColdFusion Administrator enables debugging output. The attribute's default value is Yes. The following tag suppresses all debugging output for the current page:

<cfsetting showDebugOutput="No">

You can put this tag in the initialization code of the Application.cfc file or on your Application.cfm page to suppress all debugging output for an application, and override it on specific pages by setting showDebugOutput="Yes" in cfsetting tags on those pages. Conversely, you can leave debugging on for the application, and use the cfsetting showDebugOutput="No" tag to suppress debugging on individual pages where the output could cause errors or confusion.

You can also use the showDebugOutput attribute to control debugging output if you do not have access to the ColdFusion Administrator, but only if the Administrator enables debugging.
