 * When I use your plugin the rss feed does not validate because one line is double:
   
   xmlns:media=”[http://search.yahoo.com/mrss/&#8221](http://search.yahoo.com/mrss/&#8221);
 * See this line : [https://i.imgur.com/fRYzro5.png](https://i.imgur.com/fRYzro5.png)
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fvalidation-error-79%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hi [@cedericvh](https://wordpress.org/support/users/cedericvh/)
 * There’s another plugin adding a duplicate “media” attribute. Find that plugin
   and deactivate it adding images or media to RSS. These plugins we know can cause
   this issue:
 * Conflicting Plugins
    Known conflicting plugins: RSS Link plugin Feedzy Rank Math
