Website appears different with or without "www."

Permalink
My website appears different depending on if you type inhttp://www.itwilltakeallofus.org or just itwilltakeallofus.org. The www. shows an older version of my website. I can edit them both separately but it would save a lot of time if I could just update both at the same time. Anyone know why this is happening?
Thanks

Your going to want to redirect the url that is the older one to the newer one. There is an addon called 301 redirect that can help or you can use this redirect guidehttp://www.webconfs.com/how-to-redirect-a-webpage.php... Also you may be able to have your host put this in for you.

On a side note you also seem to have two separate installs of c5 running, and each url is directed to a different version. You are going to want to clean up your servers files, and folders.
