I’m actually having a similar problem. I updated the plugin and noticed the WordPress SEO by YOAST box was minimized and it could no longer be expanded. Can’t seem to move it either, but being unable to expand the box is a bigger issue, since it makes it the box useless.
I have updated the plugin several times since the problem occurred, hoping that might fix the issue, but it did not. I would have deactivated the plugin by now, however, I keep hoping the issue will go away with the next update.
I’m running the latest version of WP (3.4.2) as of this post.
I have been having this problem over the past week also. I love this plugin and hope that it is updated to work with the newest version of WordPress.
I have the exact same issue. 🙁
Would be nice if this could be fixed. Looks like WordPress SEO might be interfering with the admin jquery.
