Hello,
We apologize for the issue you are facing with your sitemap_index.xml showing a completely white page. Since you’ve already tried several troubleshooting steps, including checking the source code and ensuring that there is content, it seems like there might be a conflict with another plugin or theme.
Here are a few additional steps you can take:
-
Check for Plugin Conflicts: Use the Health Check plugin to identify if any other plugins are causing conflicts with Rank Math.
-
Flushing Cache: Ensure that all caching mechanisms (including server-side caching) are completely cleared. Sometimes, caching plugins can interfere with the display of dynamic content like sitemaps.
-
Review Server Configuration: If you are using Nginx or Apache, ensure that the rewrite rules are correctly set up in your server configuration files as mentioned in our documentation.
- For Apache, check your
.htaccess
file for the correct rewrite rules.
- For Nginx, ensure the appropriate rewrite rules are added to your Nginx config file.
-
Disable Other Plugins Temporarily: If possible, try disabling other plugins temporarily to see if the sitemap loads correctly without them.
-
Theme Conflict: Switch to a default WordPress theme (like Twenty Twenty-One) to see if the issue persists. This can help determine if your current theme is causing the problem.
If none of these steps resolve the issue, we recommend replying to this ticket so a human agent from the Rank Math Support team can assist you further. Thank you for your patience!
Hello,
We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.
Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
https://wordpress.org/plugins/temporary-login-without-password/
You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

Looking forward to helping you.
Thank you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hello,
let me know when you finish with debugging.
Hello,
The issue is coming from the Пресловљавање plugin. This plugin converts the HTML code to the actual symbols in the page source of the sitemap stylesheet, and that’s why the sitemap isn’t loading. Please get in touch with their support and ask them to exclude the sitemap files to fix the issue.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
Hi,
I checked your statement.
I disabled that plugin but still sitemap_index is completely white.
Should I do something else?
Hello,
We can see it working if we disable that plugin as you can see from our screencast we shared in the sensitive data section.
Once you deactivate the plugin from your end, please make sure to clear the browser caches first before visiting the sitemap.
Don’t hesitate to get in touch with us if you have any other questions.
