One of the first plugins I installed on my website, was the WordPress SEO plugin by Yoast. A great tool to enhance your on site search engine optimization and this all for free. (Although the author seems to appreciate some gifts.)
You’ll find detailed information about the WordPress SEO Plugin on it’s own website http://yoast.com/wordpress/seo/.
“Call to undefined function update_options()”
Recently, an update to the newest version 18.104.22.168 has become available. This update should work with WordPress 3.4.1. The update went real smooth from within the backend of WordPress. However, a fatal error occurred as soon as you tried to navigate to a page or your backend.
PHP Fatal error: Call to undefined function update_options() in /path/to/your/wordpress/root/wp-content/plugins/wordpress-seo/admin/class-admin.php on line 441
Correct line 441 in the file /path/to/your/wordpress/root/wp-content/plugins/wordpress-seo/admin/class-admin.php
Apparantly, there’s a little typo in the php file class-admin.php on line 441. This is the original statement:
update_options( 'wpseo', $options );
You have to change this line to:
update_option( 'wpseo', $options );
Don’t forget to save your file! Now you should be able to navigate to your website or backend again.
