WordPress redirect loop with DH hosted site


I’ve run into a DNS (?) redirect problem on a new site. Essentially when going to http://sitename.org I get infinitely redirected to http://www.sitenamei.org and back again.

My own follow-up: This came about because I created the WordPress site with one redirect setting (keep sitename.org and www.sitename.org) and then changed this setting to remove www afterwards.
