Configure your sites error reporting
Last modified: October 21, 2007 - 23:54
Where Drupal, PHP and SQL errors are logged. On a production server it is recommended that errors are only written to the error log. On a test server it can be helpful to write logs to the screen. By default, errors are displayed to the screen. You should change this to 'Write errors only to log' only for your production site.
You can tell Drupal to automatically discard error log entries older than the age you specify. This requires a crontab (example.com/cron.php) to be set up. See step 6 of the install.txt for example of setup.

errors on screen for admin only?
hi,
the path to set the delay to discard log entries is /admin/settings/error-reporting and I also see an option called Error reporting: that proposes to Write errors on the log or Write errors on the log and to the screen, but do you know
if it is possible to write the errors on the screen only for the admin and not for any user ?
Thanks a lot!
