[Plugin: Better WP Security] Reset settings (feature reguest)

This depends on what you turned on. There are settings in your options table in your database, 2 tables of it’s own, a section it can write to .htaccess, and information it can write to wp-config.php. Note that in wp-config.php just changing items back to default such as the database prefix of if you moved wp-content it could really cause you some problems.
