How to Fix WordPress RSS Feed Errors

Are your WordPress RSS feeds not working properly? RSS feed errors can break email campaigns, podcast syndications, and content updates on aggregators. Luckily, most RSS issues in WordPress are caused by formatting errors and are easy to fix.

Here’s a step-by-step guide to troubleshoot and resolve common WordPress RSS feed problems.

Common RSS Feed Errors

- XML Parsing Error: XML or text declaration not at start of entity
- This page contains the following errors...
- RSS feed not updating or showing blank
- Feed shows unexpected characters or code

Step-by-Step: How to Fix RSS Feed Issues in WordPress

1. Validate Your RSS Feed

First, check if your feed is actually broken.

- Visit your feed URL: yourdomain.com/feed/
- Copy the feed URL and paste it into a validator like https://validator.w3.org/feed/
- Review the errors returned (often malformed XML or extra characters)

2. Disable Recently Added Code

RSS feeds are extremely sensitive to extra spaces or characters.

- If you recently edited your theme’s functions.php file, review the changes
- Make sure there’s no whitespace before `<?php` or after `?>`
- Remove any echo, print, or debugging statements

3. Switch to a Default Theme

A corrupted or misconfigured theme can break your RSS feed.

- Go to wp-content/themes in File Manager (via cPanel)
- Rename your current theme folder (e.g., astra to astra_old)
- WordPress will default to a theme like Twenty Twenty-Four

Test your RSS feed again.

4. Deactivate All Plugins

Plugins that modify content, RSS feeds, or caching can cause errors.

- Rename the plugins folder to plugins_old via wp-content
- Reload your feed to check if it works
- If it does, rename the folder back and reactivate plugins one by one to isolate the issue

5. Repair Corrupt Functions.php or Custom Code

Often, developers or users add custom code to functions.php without closing brackets or proper syntax.

- Open wp-content/themes/your-theme/functions.php
- Make sure all functions are wrapped properly and all brackets `{}` and parentheses `()` are closed

6. Use a Plugin to Rebuild the Feed

You can use plugins like “Fix My Feed RSS Repair” or “WP RSS Aggregator” to help repair or manage feeds.

- Install and activate the plugin
- Run a feed check or rebuild from plugin settings

7. Clear Caches

If you’re using a caching plugin or CDN:

- Clear all plugin caches (W3 Total Cache, WP Super Cache, etc.)
- Purge CDN cache (e.g., Cloudflare)
- Test the feed again

Final Thoughts

RSS feed errors in WordPress are typically caused by formatting issues in theme files or interference from plugins. With a few quick fixes and tools like cPanel File Manager, you can restore your feed in no time.
