JKG Posted July 11, 2011 Share Posted July 11, 2011 all to do with header errors, but the reason it will have just started showing them is your error settings will be different on your live server to your local one.

premiso Posted July 11, 2011 Share Posted July 11, 2011 all to do with header errors, but the reason it will have just started showing them is your error settings will be different on your live server to your local one. Or his local server has output buffering enabled.
