I’m not seeing this occurring.
If you run the site in question against https://validator.w3.org/feed/ it shows the same thing?
If you turn off External Links, it then validates (assuming it didn’t above)?
What are your External Link settings? If Apply Globally is checked can you uncheck and test it again?
It is also possible there is a conflict with another plugin. The Apply Globally should be telling if it passes with it off and fails with it on.
Yes, when the Reading Settings are set to “full text” you get the error above. When it is set to “Summary” you do not get the error and the feed validates.
It took me a full day to figure out what was causing this problem, so I deactivated all plugins and re-activated one-by-one and External Links was the one causing the problem.
If “Apply Globally” is un-checked, the feed validates. When checked, it does not validate.
What theme are you using for your site?
Can I ask questions with you guys? i really need a plugins that are not existing yet, or maybe not working? just for my thesis. help me guys, thank you in advance ^_^
What is your thesis statement? I think most plugins probably have been created in some fashion. It depends on what problem the plugin is attempting to solve.
