Are you having RSS feed errors on your WordPress site? RSS feeds allow users to subscribe to your blog through tools such as Feedly. However, because RSS feeds use the XML markup language, even minor errors might render the feed useless.

It also means that users will not see your fresh content in their news feeds. With this guide, we will show you how to quickly resolve RSS feed errors with WordPress. We will also talk about what causes these problems and how to prevent them in the future.

The Most Common WordPress RSS Feed Errors

The most common WordPress RSS feed errors are caused by poor formatting. WordPress creates RSS feeds using a strict XML markup language. A missed line break or an extra tab can cause your WordPress blog’s RSS feed to fail.

The RSS error message will appear like this:

XML Parsing Error: XML or text declaration not at start of entity
Location: http://example.com/feed
Line Number 2, Column 1:

Depending on the browser you’re using, your RSS feed error message might vary.

When you view your feed in a browser, you might get this error message:

Warning: Cannot modify header information – headers already sent by (output started at /home/username/example.com/wp-content/themes/functions.php:433) in /home/username/example.com/wp-includes/pluggable.php, line 1228

The error messages may alter if you use FeedBurner or other social sharing automation apps, such as IFTTT. This error not only damages your feed but can also cause issues for services that rely on your WordPress RSS feed to send content updates to subscribers.

Having stated that, let’s look at what’s causing these RSS feed issues and how to fix them. You can use these quick links to jump to a specific step.

Manually Fixing RSS Feed Errors in WordPress

To manually fix RSS feed errors with WordPress, you’ll frequently need to rectify incorrect formatting. This formatting error is commonly caused by an extra space after the ending PHP tag in your plugin or theme’s functions.php file. If you recently added a code snippet to your theme or child theme’s functions.php file, you should open and edit it.

One thing to check is that there is no PHP closing tag at the end of the file, as this is not required. If there is a closing PHP tag after your functions file, you must either remove It or make sure no blank spaces or line breaks follow it, as seen below. Note how there are no lines or spaces after the ?>.

// Your PHP code here
 
?>

We also do not recommend modifying your theme files with the default theme editor. Instead, you can use WPCode to add code snippets in the future. This plugin allows you to insert code snippets into your website without modifying the functions.php file.

Furthermore, its smart code validation will aid in the prevention of frequent code problems that could cause your website to fail.

However, if this does not resolve your RSS feed error, continue reading.

Disable RSS Feed Related Plugins

If you’re using a WordPress plugin that changes or creates your website’s RSS feed, you should disable it. If you are unsure, you can temporarily turn off all WordPress plugins.

Simply navigate to Plugins > Installed Plugins in the WordPress admin dashboard. Then, click the box in the top-left corner of the plugins list and select ‘Deactivate‘ from the ‘Bulk actions’ selection.

Finally, click ‘Apply‘.

Next, check your RSS feed for any errors. If the error goes away, it was caused by one of the WordPress plugins you had installed. You can now reactivate your installed plugins one at a time, checking your RSS feed after each activation. In this manner, you can determine which plugin is causing the problem.

Once you’ve found the plugin, you may contact its support team to request an update or discover another plugin that does the same job. Check out our top selections for the best WordPress RSS feed plugins to find a suitable replacement.

Temporarily Switch to a Default Theme

Occasionally, a badly coded WordPress theme function can interfere with your RSS feed. To determine whether the problem is caused by your WordPress theme, briefly switch to the default WordPress theme. Simply navigate to the Appearance » Themes page and, if you have a default theme loaded, activate it.

Default themes include Twenty Twenty-Three, Twenty Twenty-Two, and so on.

If you don’t already have one, install one in WordPress. Step-by-step instructions may be found in our WordPress theme installation guide.

After changing to the default theme, check your WordPress feed for issues. You can check your feed in a browser window or use a feed validator tool.

If the error disappears, it signifies that the problem was caused by your WordPress theme. You can contact the theme author for assistance or find a new WordPress theme for your website.
