If you are using Rank Math SEO plugin and suddenly your sitemap URL shows a 404 error, don’t panic. This is a very common issue in WordPress websites and it can usually be fixed in a few simple steps.

Earlier your sitemap was working fine, but now when you try to open:

It shows a 404 Page Not Found error.

In this detailed guide, I will explain:

• Why Rank Math sitemap shows 404
• What causes this issue
• Step-by-step solutions to fix it
• Advanced troubleshooting tips

What Is Rank Math Sitemap?

Rank Math is a powerful WordPress SEO plugin that automatically generates XML sitemaps for your website.

The sitemap helps search engines like:

• Google
• Bing

to crawl and index your website properly.

The default sitemap URL in Rank Math is:

yourdomain.com/sitemap_index.xml

If this URL returns 404, search engines cannot access your sitemap — and this can affect your SEO.

Why Rank Math Sitemap Shows 404 Error?

Here are the most common reasons:

1️⃣ Permalinks Need to Be Refreshed

WordPress rewrite rules sometimes break.

2️⃣ Sitemap Feature Disabled

Sitemap option might be turned off accidentally.

3️⃣ Plugin Conflict

Another SEO or caching plugin may conflict.

4️⃣ .htaccess File Issue

Missing or corrupted rewrite rules.

5️⃣ Cache Problem

Old cache files may cause the sitemap to not load.

How to Fix Rank Math Sitemap 404 Error (Step-by-Step)

Step 1: Refresh Permalinks (Most Important Fix)

This solves 80% of cases.

1. Go to WordPress Dashboard
2. Click Settings → Permalinks
3. Do NOT change anything
4. Click Save Changes

Now open:

yourdomain.com/sitemap_index.xml

In most cases, the problem will be fixed.

Step 2: Make Sure Sitemap Is Enabled

1. Go to Rank Math → Sitemap Settings
2. Check if Sitemaps are enabled
3. Save changes

If disabled, enable it and test again.

Step 3: Clear All Cache

If you use caching plugins like:

• LiteSpeed Cache
• WP Rocket
• W3 Total Cache

Clear all cache.

Also clear:

• Browser cache
• Hosting/server cache

Then test the sitemap again.

Step 4: Deactivate Other SEO Plugins

If you previously used:

• Yoast SEO
• All in One SEO

Deactivate them completely.

Two SEO plugins at the same time can break sitemap URLs.

Step 5: Check Correct Sitemap URL

With Rank Math, correct URL is:

https://yourdomain.com/sitemap_index.xml

Sometimes users try:

/sitemap.xml

That may not work depending on settings.

Step 6: Fix .htaccess File (Advanced Fix)

If the issue still exists:

1. Go to cPanel → File Manager
2. Open .htaccess file
3. Make sure it contains default WordPress code:

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress

If missing, add it and save.

✅ Step 7: Check Plugin Conflicts

Deactivate all plugins except Rank Math.

Then test the sitemap.

If it works → activate plugins one by one to find the conflicting plugin.

Special Cases

🔹 If You Recently Migrated Website

Re-save permalinks and regenerate sitemap.

🔹 If You Changed Theme

Sometimes themes conflict with rewrite rules.

🔹 If You’re Using LiteSpeed Hosting

Purge all cache from LiteSpeed panel.

How to Test Sitemap Properly

After fixing:

1. Open sitemap URL in browser
2. Submit it in Google Search Console
3. Check if it shows “Success”

Final Checklist

✔ Permalinks refreshed
✔ Sitemap enabled
✔ Cache cleared
✔ No SEO plugin conflict
✔ .htaccess correct
✔ Correct URL used

• Broken rewrite rules
• Cache issues

The good news is — it is easy to fix.

Just follow the steps carefully, and your sitemap will start working again.

If your sitemap still shows 404 after trying everything, the issue may be server-level, and you should contact your hosting support.
