Support » Plugins » RSS Validation Error using Yoast SEO and Magic Fields Plugins

  • Two great plugins, but something is not working right.

    These Plugins or combination of these plugin results in an error in the RSS feed :-

    Cannot modify header information – headers already sent by

    WordPress version 3.5.1
    Magic Fields Plugin Version 2.1 ( www/ )
    WordPress SEO By Joost De Valk Version ( )

    Background Information
    The problem occurred on the website, the RSS feed having this error. The error can be checked by using the W3C Feed Validation Service

    enter the URL

    A copy of this website has been installed in the following URL

    This just being a spare url I can use for some testing.

    The custom theme that was used in the original website has been removed and the theme has been set back to the default 2010 WordPress theme.

    The website looks a complete mess, but is essentially functional.
    All Plugins apart for the Magic Fields and The WordPress SEO have been removed.

    All magic fields have been removed. So the installation in has been reduced to the bare bones.

    If either plugin is deactivated the RSS validation error goes away.
    Use the w3C validator with is the error condition.

    Anyone any insight into how I can resolve this issue ?
