I’m getting a “Call to undefined function filter_input()” error
If you’re getting the following error, it means that your hosting setup has disabled a PHP filter extension that our plugin relies on.
Fatal error: Call to undefined function filter_input() in /PATH_TO_WORDPRESS/wp-content/plugins/wordpress-seo-premium/PATH_TO_FILE.extension on line ###
This feature is enabled by default in most setups, so shouldn’t generally be disabled.
Unfortunately, unless you’re an administrator on the server, you can’t solve the problems yourself. You’ll need to contact your hosting company and ask them to enable the extension.
