**LOG_TARGET_ADMIN**: Show error messages on the screen, but only when you are in the *Administration* area.

**LOG_TARGET_ERRORLOG**: Send log information to the error log as specified in your Apache configuration. It is recommended to use this setting for all log levels no matter the other targets that you specified.

92.

**LOG_TARGET_FILE**: This allows you to specify a file to which messages will be logged. It's best to pick a path in dataroot, but note that log files tend to get very large over time. So it's advisable to implement some kind of logrotate if you want to leave this on all the time. The other option is to just turn this option on when you are getting a specific error or want to see the logging, and know that you're not going to let the log file get large.

You can combine the targets with bitwise operations, e.g. ``LOG_TARGET_SCREEN | LOG_TARGET_ERRORLOG``.

If you use LOG_TARGET_FILE, this is the file to which errors will be logged. By default, it will write to the file ``error.log`` under the dataroot. If you change this in config.php, make sure you use a folder which is writable by the web server.
