I turned my WordPress site to multisite with WP Empire Builder but need to restore my site back to normal

Please edit wp-config.php and change define('MULTISITE', 1); to define('MULTISITE', 0);

This will simply switch WP back to single site mode but our other modifications will still be in place.

You can also easily turn multisite back on with Empire Builder and all your child sites and network configuration will be restored.

You can completely restore files we changed (wp-config.php and .htaccess) from empire_builder-backup/files folder. Just find the files wp-config.php and .htaccess in that folder, copy them and paste them at the root of your blog, where the modified wp-config.php and .htaccess exist - and overwrite those files.
