I’ve installed wordpress in “/wordpress” and not in the site root, so the wordpress site is now accessible only from http://www.mysite.com/wordpress/.
How can I move wordpress to the site root (so it can be accessible from http://www.mysite.com) and make it work correctly?
Thanks
Are you locked out on your site? you might need to modify the database to point to the new url
Follow these steps

the database you need to modify are siteurl, home in the wp_options table
