The post editor is not full functioning with WordPress SEO turned on. Specifically, the media uploader opens in a new window and then does insert and return to the post when you click insert. Also, you can not edit the pretty permalink. Nothing happens when you click "Edit". There may be others, but these are the ones I have noticed.
I am running a good number of plugins and have tried debugging each of them with WordPress SEO to see if there is a plugin conflict... It seems that there is a conflict with FAQ Builder Version 0.6 Beta.
Let me know if there is any fix for this. Thanks!
