    I have several of our dealer websites (13) that are having a problem creating a siteindex.xml file. The error message I get is: Error loading stylesheet: Parsing an XSLT stylesheet failed.

    The sites share a common Yoast anomoly namely: on the Yoast SEO settings>Site Features area – all the little icons are missing in every section ex. AI tools, Writing and etc. I have all the switches activated to ON. I have deactivated Yoast, deleted it, reinstalled and save permanlinks but I get the same blank images and the same error message when trying to view the sitemap.xml file. Yoast dashboard showing not apparent problems. Not sure if the lost images relate to the problem or not, but the other sites where the images are visible, the website can generate the sitemap.xml. Any help would be appreciated.

    Hi @rbjork,
    Parsing XSLT stylesheet failed + missing Yoast icons = asset loading problem. Your server can’t load Yoast’s CSS/JS/XSL files.
    The reason likely:
    server-level issue blocking Yoast assets: CDN/Firewall blocking requests, Maybe file permissions problem, ModSecurity rules can blocking .xsl files.

    Quick diagnosti test:
    Check if XSL file exists. Try to accessing directly: yourwebsite.com/wp-content/plugins/wordpress-seo/css/main-sitemap.xsl

    If found 403/404 error = file permissions or server block

    Check browser console:

    Open any Yoast settings page
    Press F12 → Console tab
    Look for 403/404 errors on Yoast asset URLs

    Share what errors you see
