We are sorry to hear that after updating the Yoast SEO plugin, it broke your website. We totally understand how that could be frustrating for you. Let’s see what’s going on here.
First thing first, if you no longer have access to your site or if your website is down, please reach out to your web hosting provider and ask them to restore your website to a previous state.
Alternatively, if you are familiar with the FTP (File Transfer Protocol), you can log into your server and manually remove the wordpress-seo
folder from your website’s WordPress installation /wp-content/plugins/
directory and that shall bring your website back.
That said, can you please what version of the WordPress you are currently running? What Yoast SEO version you were using before updating it to the latest version? Do you see any errors when the Yoast SEO update broke your website?
