('binary' encoding is not supported, stored as-is) In-Reply-To: <1059078080.10973.171.camelat_private> The db_dump code is protected against non-logged in users as are all admin functions. If a registered member with full admin permissions (not any admin, it -has- to be the main site admin who installed e107 in the first place) is not seen then the login page is displayed. This has always been the case, however if anyone is worried about this in any way delete the db.php file in your /admin directory and use phpMyAdmin or similar to perform database backups.
