Hello,
We apologize for the inconvenience you are facing with your sitemap. If you have already cleared the cache and added the sitemap to the list of pages not to be cached, there might be a few other reasons why your page is not included in the sitemap.
One reason could be that the page is set as “Noindex.” You can check this by clicking on the Advanced tab settings of that particular post or page. If the Robots Meta tag is set to Noindex, then that’s why your URL is not appearing in the sitemap. To fix this, simply change the Robots Meta tag from Noindex to Index and save your changes.
If the issue persists, you can also check if the page is excluded from the sitemap settings of Rank Math. To include the page in your sitemap, navigate to Rank Math SEO → Sitemap Settings and ensure that the page is not excluded from the sitemap.
If you still face any issues with the specific page not appearing in your sitemap, please feel free to contact our dedicated support team here. We are available 24/7, 365 days a year and will be more than happy to assist you further.
We hope this helps!
