An audit trail is a step-by-step sequential record that offers evidence of a financial transaction's documented history back to its source. With the use of the audit trail, an auditor can track the financial data of a specific transaction from the general ledger to its source document. Audit Trail is a live record of changes on your site – it keeps a log of everything that’s ever happened. Any changes made to properties, taxonomies, terms or users will automatically be recorded in the audit trail table. This includes the changes which are not visible to the end user: updating unpublished post or pages, deleting archived items, editing user profiles, etc.
