The problem is being caused by a bad plugin or theme file. Mcnute's answer, while it will work (except you can't edit the core from the backend, need to use FTP), involves changing core WordPress files and as soon as WordPress updates the changes will be lost and the problem will return.
You would be better off isolating the problem file by deactivating all plugins and then reactivating one at a time until the problem reappears or searching through the theme to see where headers are being sent and attempting to comment out those lines.

That's because you send something to the client before all php code has been executed and this is against w3c standards that headers must be sent before any content and only in this order headers->content.
