the steps to enable multi-site:
1,insert below into wp-config.php;
define(‘WP_ALLOW_MULTISITE’, true);
2,create a folder named “blogs.dir” in /wp-content/blogs.dir;
3,copy codes in tools-network menu to wp-config.php and .htaccess file;
i think you can easily find more detail steps info by google;
i exported .cctm.json from V0.9.3.3 and imported to another V0.9.3.3, failed;
haven’t try V0.9.4.2 yet….but i guess the same….it should not be related to version…..unless it’s a issue you have know before V0.9.4.2 and you fixed it with plan.
