Custom Post Type Sitemap 404 Error

Hello,

I’m sorry to hear that you are facing issues with your custom post type sitemap showing a 404 error in Rank Math. If you have already updated the permalink structure and added the sitemap URLs to the exclude list in your caching plugin (Nitropack), there are a few more steps you can take to troubleshoot this issue.

1. Flush the Sitemap Cache: After making changes, it’s essential to flush the sitemap cache for the modifications to take effect. You can do this by navigating to Rank Math SEO → Sitemap Settings and changing the Links Per Sitemap as shown in the screenshot below:

Remember to click on Save Changes to apply the settings.

2. Ensure Pages Are Set to Index: Check if your custom post type pages are set to index in the robots meta tag. Pages set to noindex will be excluded from the sitemap generated by Rank Math, leading to a 404 error. You can verify this by navigating to Rank Math SEO → Advanced tab in the post editing screen as shown in the screenshot below:

Make sure to save the changes by clicking the Update or Publish button.

If the issue persists after following these steps, please feel free to reach out to our dedicated support team for further assistance. You can contact them here. Our team is available 24/7, 365 days a year to help you with any problems you encounter.

I hope this information helps resolve your custom post type sitemap 404 error. If you have any more questions or need additional assistance, please let us know.
