I am seeing a "It looks like your .htaccess file is not writable" error

SmartCache is trying to automatically update your site’s .htaccess file after you made some changes. If you are able locate the .htaccess file (normally in your site’s root folder — /public/domain, /var/www/domain/htdocs, etc.) and set its permissions to 666. Resave the settings. Reset the .htaccess file permissions back to 644 or 444.
