    Hi there,

    Based on that error, the issue is being caused by the Yoast SEO plugin, so please contact their support directly for help with this.

    You can find the forums for the free version of Yoast SEO at https://wordpress.org/support/plugin/wordpress-seo/, or if you’re using the premium version of that plugin, you should be able to contact support via their website.
