When the debug is on, does the error messages go to a separate log file or CF display it on the page? It goes to a separate log file. The location varies by install type, but from the documenation: yes : sends debugging output to standard output. By default, if the console window is unavailable, ColdFusion sends output to cf_root\runtime\logs\coldfusion-out.log on server configurations. On J2EE configurations, with JRun, the default location is jrun_home/logs/servername-out.log. Caution: If you set this option to yes , ColdFusion writes detailed debugging information to the log, including all message contents, and can generate large logs quickly. no : does not generate debugging output.
