no access to wp console after changed console/general settings/website url

I changed console/general settings/website url from http://xxxxx/wordpress to spmething else and now I have no access to console because even
http://xxxxx/wordpress/admin or
http://xxxxx/wordpress/wp-admin
redirects me to http://xxxxx/wordpress and doesnt loads any template theme, just plain text and pictures on white background.

is there a file I should edit in ftp to switch it back?
