Hi Joost,
thanks for your great plugin.
I just noticed that when you disable the WP SEO metabox for a post type (in the SEO Dashboard) there is a javascript error in the "Add New" screen:
Error: wpseo_meta_desc_length is not defined
Source File: http://mypage.com/wp-content/plugins/wordpress-seo/js/wp-seo-metabox.js?ver=3.1
Line: 247
Wouldn't it be better if the javascript file was unloaded on pages where the SEO metabox is disabled anyway?
Cheers,
Axel
