Very nice and simple fix and it worked for me. It is one of those problems so easily overlooked. Deleting the blank line before the did the trick. I used this in a stand-alone download application using PHP and Octets with IE7 from a Linux server. Thanks for the help, John http://rmtrain.com.

Thank you so much, I had error messages all over my page, and it was from one of my new plugins. I have never mucked around in PHP land, and with your simple instructions, I knew what to do. Thank you so much, I’ll start uploading my plugins with caution.

In the instance a plugin could be causing the problem, all you need to do is download all the plugins you’re using off your server, then delete them off the server. Then you can upload them and activate one by one until you find the one causing the error.
