Fix for error caused by updating Yoast WordPress SEO plugin

I logged into one of my WordPress sites today and noticed that the (normally) excellent WordPress SEO plugin by Yoast needed to be updated. I updated as usual and then noticed that my dashboard returned a 500 Internal Server Error.

Turns out that the latest update released by Yoast caused this error. I turned on debug in my WP Config file and got more details about this error:

“Fatal error: Call to undefined function update_options() in ../httpdocs/wp-content/plugins/wordpress-seo/admin/class-admin.php on line 441”

If you have FTP access to your files, you can fix this error by following these steps:

• Find the file that is causing the error: “wp-content/plugins/wordpress-seo/admin/class-admin.php”
• Go to line 441
• Change update_options to update_option
• Save the file and reload your dashboard – it should work again
