 * This may be a plugin or theme conflict. Please attempt to disable all plugins,
   and switch to the default Twenty Twenty-One theme. If the problem goes away, 
   enable them one by one to identify the source of the problem.

 * Hi, James Huff
    Thank you for the advice, I’ve tried deactivating the plugin,
   changing to the default theme and clearing the cache, but the code xmlns: media
   = “[http://search.yahoo.com/mrss/&#8221](http://search.yahoo.com/mrss/&#8221);
   xmlns: media = “[http://search.yahoo.com/mrss](http://search.yahoo.com/mrss) /“
   > still showing up.
 * any other way to fix it?
 * thank you

 * That’s so weird, it’s not part of default WordPress in any way.
 * What plugins are you using?

 * Yeah, clear the proxy cache too, but with all plugins deactivated and the Twenty
   Twenty-One theme in use.

 * Thank you for the help,
    it turns out that this is the cache of the proxy. I’ve
   been through hard times 😀 Thank you and always be healthy.
