  • Hi @iarovuo

    We are sorry to hear about the issue you are having with our plugin! Can you please confirm if the error persists even with the latest Yoast SEO 13.3? Can you confirm if your site matches the plugin requirements here?

    Hi @jerparx,

    We have deleted all transients with name starting yst_ and following situation.

    It seems this has resolved the issue – although we have no details how transients got corrupted. Maybe a worth to provide an option, or automate transient clearing when corruption is noticed.

    Since Yoast SEO 9.0 this feature is disabled by default:

    Improves sitemap performance by disabling the caching by default.

    Divi forces this kind of caching ( you can look file includes/builder/plugin-compat/wordpress-seo.php ). You can use the filter wpseo_enable_xml_sitemap_transient_caching (with higher priority) to disable it.
