Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
I am terribly sorry to inform you that a minor technical error occurred during the troubleshooting process. which caused the critical error on your website.
To fix the issue immediately, please login using your cPanel/FTP, and head over to /wp-content/plugins/seo-by-rank-math/includes/modules/sitemap, find the file named ss.php and rename it to class-redirect-core-sitemaps.php.
If that doesn’t resolves the error, please upload the file to the same directory I’ve shared with you in the sensitive data section.
As for the blank sitemap issue, there was an error:
Error loading stylesheet: A network error occurred loading an XSLT stylesheet:
Which preventing your sitemap from loading. We often noticed that deleting and re-generating sitemap works in this type of situation. Please try that to see if this resolves the issue.
Looking forward to helping you.
Thank you.
