 * When attempting to validate my RSS feed (for use with Mailchimp, IFTTT etc.) 
   using [https://validator.w3.org/feed/](https://validator.w3.org/feed/) the following
   error is returned:
 * This feed does not validate.
    line 8, column 98: XML parsing error: <unknown>:
   8:98: duplicate attribute
 * Inserted into the feed is the code:
 * `xmlns:georss="http://www.georss.org/georss" xmlns:geo="http://www.w3.org/2003/
   01/geo/wgs84_pos#" xmlns:georss="http://www.georss.org/georss" xmlns:geo="http://
   www.w3.org/2003/01/geo/wgs84_pos#" >`
 * Wherein lies the duplicate attributes. I have tried re-saving blog posts that
   contain locations to remedy the issue to no avail.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Finvalid-feed-duplicate-attribute%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * I see it in yours, but not in mine. Is it possible you have multiple plugins 
   that are trying to add georss to your feed? Do you have any other location plugins
   installed?

 * Thank you for taking a look. I’ve got a number of plugins installed but non that
   I can easily discern are trying to add georss. I have a number of IndieWeb extensions
   installed:
    - WebMention
    - Semantic Linkbacks
    - Micropub
    - Post Kinds
    - Syndication Links
    - Bridgy for WordPress
    - IndieAuth
    - Microformats 2 (deactivated)
    - Simple Location
    - WebSub/PubSubHubbub
 * In addition to:
    - Cloudflare
    - Jetpack for WordPress.com
    - Smush
    - Yoast SEO
 * I’ll try disabling the plugins one-by-one and see how it get on.

 * Turns out this came from Jetpack, which added duplicate data last year. It has
   been resolved in the latest development version, will be released soon.
