The problem is when posting. Client was making edits on pages but clicking update caused the 405 not allowed nginx error.
I went through all the plugins and wp-seo-meta was the problem. maybe a conflict with another plugin? The only thing new that happened was maybe the wordpress update to 4.5.1
Bigger problem is 2 days my associate spent creating meta descriptions. They don’t appear on reactivate. Hope there is a solution to that.
Despite this, congratulations on your work. It is very good.
