How to Fix WordPress RSS Feed Errors

RSS Feed Errors

Have you encountered RSS feed errors on your WordPress site? RSS feeds enable users to subscribe to your blog using news readers like The Old Reader or Feedbin.

Because RSS feeds are published in XML markup, a single misplaced comma can ruin a feed, making it unreadable for users.

WordPress RSS feeds are also an important source of content for some other apps. For example, if you use IFTTT to promote your posts on social networks, then that won’t work too.

Throughout this article, you will learn how to fix RSS feed errors in WordPress. In addition, we will discuss what caused these errors and how they may be prevented in the future.

Why RSS Feed Errors In WordPress Occur?

Knowing how RSS works first will help you to better understand RSS errors. It is especially important for you to know that your RSS feed is created in XML, a markup language that facilitates data sharing.

The structure of the XML document must be extremely precise to function appropriately. Even something as simple as misplaced line breaks can ruin it. The most common WordPress RSS feed errors can be attributed to this problem.

A badly coded RSS plugin is another possible cause. Errors can indeed be caused by compatibility issues between plugins.

Finally, themes are less common but still notable culprits when it comes to WordPress RSS feed errors. There may be a layout issue that is preventing your RSS feed from generating properly, or a feature provided by your theme may conflict with your feed.

Your code is generally the cause of RSS feed errors in WordPress. Hopefully, you don’t need any prior experience with XML to fix the issue.

WordPress RSS Feed Errors: How To Rectify Them Manually

Your RSS feeds showing errors most likely come from poor formatting, like an apparent blank space after the closing PHP tag in a plugin or in the functions.php file related to your theme.

There should not be any extra space or line breaks following a PHP closing tag in your functions file.

Ideally, closing PHP tags are not necessary at the end of a file. Therefore, you should remove this tag from your code entirely.

The functions.php file can be accessed in two ways.

Use a FTP client like FileZilla to connect to your server if you’re comfortable with FTP. Locate functions.php in wp-content > themes > your-active-theme. Then, open the file and check there is no extra space or line breaks at the end of the file, or remove the tag.

If you prefer, you can also log on to your site and go to Appearance > Theme Editor and edit functions.php from there. Scroll to the bottom and remove the php tag.
