Updating this plugin to last version, it's impossible to me to access to my posts and other configurations of my backend. I can only click backward by my keyboard, deactivate plugin SEO by Yoast and then everything is ok.
It seems the same problem of old 1.2.8.1: http://wordpress.org/support/topic/plugin-wordpress-seo-by-yoast-1281-breaks-admin/page/2
What can I do?
