Where are the watchdog logs located or how do I view the errors created? How do I view the watchdog logs that are created? Is there an interface to view them with, or are the logs stored somewhere on the filesystem?
Both Drupal 6 and Drupal 7 put the viewable version of watchdog logs at /admin/reports/dblog. The core database logging module needs to be enabled, and users who want to view them need the access site reports permission. The actual database table is watchdog.
