Mastering Technical SEO Debugging: Your Sitemap Rescue Plan

Blank XML sitemaps are a nightmare. They stop search engines in their tracks. And that’s exactly why Technical SEO Debugging matters. You need to hunt down hidden errors, missing database entries or snippet failures. Then you patch them up. Simple? Not really. It’s fiddly. It’s time-consuming. But it’s also mission-critical for indexing.

We’ll walk you through a no-nonsense, two-pronged approach: the hands-on, manual method and the smarter, AI-powered way. You’ll learn to spot common pitfalls, fix them one by one, and then automate prevention. Ready to transform your troubleshooting routine? Unlocking the Future of Marketing with CMO.SO through Technical SEO Debugging shows you how to combine AI-driven insights with real-time visibility tracking for flawless indexing.

Why Your XML Sitemap Is Blank

A blank XML sitemap looks like this:

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
        xmlns:xhtml="http://www.w3.org/1999/xhtml">
</urlset>

No URLs. No clues. Here are the usual suspects:

• Plugin setup issues
  Snippets or extras fail silently if they can’t write to a table.
• Missing database entries
  Thousands of pages—all missing from the sitemap—because the plugin never created default records.
• Version mismatches
  An older plugin on a newer PHP or CMS version can throw cryptic errors.
• Hidden PHP errors
  You might see nothing until you check the error logs.

One real example comes from a community user on MODX. Their sitemap snippet output was empty due to a missing table (modx_seosuite_social). They reinstalled the plugin, but only resaving each resource one by one repopulated the sitemap. Painful.

Spotting the Errors

• Check your CMS error log for “Table doesn’t exist” or “Unknown column”.
• Run a quick SQL query to see if the table modx_seosuite_resource or its equivalent has rows.
• Try resaving a single page in the manager and watch the sitemap update.

That’s the classic debug path. Now, let’s explore how to speed this up with modern SEO tooling.

The Classic Manual Approach

You’re on your own, troubleshooting step by step:

1. Dive into logs.
2. Identify missing or corrupt tables.
3. Write an SQL script to create default entries:

sql
INSERT INTO modx_seosuite_resource (resource_id, uri)
SELECT id, uri FROM modx_site_content
WHERE id NOT IN (SELECT resource_id FROM modx_seosuite_resource);

4. Run the script.
5. Trigger a sitemap rebuild.

On small sites, this works. But on sites with hundreds or thousands of pages, it’s tedious. You miss one entry. Bam—you’re back to a blank sitemap.
