Hi I have resolved by running this DB query:
UPDATE wp_options SET option_value = replace(option_value, ‘http://www.old-url.com’, ‘http://www.new-url.com’) WHERE option_name = ‘home’ OR option_name = ‘siteurl’;
UPDATE wp_posts SET guid = replace(guid, ‘http://www.old-url.com’,’http://www.new-url.com’);
UPDATE wp_posts SET post_content = replace(post_content, ‘http://www.old-url.com’, ‘http://www.new-url.com’);
Thanks 🙂
No, I simply copied all the site files into the “new” sub-domain folder.
Thanks.
