I just had the exact same thing happen. When I went to edit posts, the layout of the admin was so garbled that it was impossible to edit posts. I deactivated all plugins and the problem went away. Then I activated the plugins again one by one and checked to see if the problem returned. The problem returned when I activated this plugin.
I depend on this plugin for a variety of reasons but unfortunately it’s unusable right now.
I’m running WP 4.9.4 with the latest version of the Florence theme, and the latest version of this plugin.
