I do not have that checkbox. I am also unable to edit, trash, nor delete pages created by SLP. From the manage location section when I click edit I get an error that states I am not allowed to edit that page.
My page template is unchanged. I changed the theme to see if that was the issue and I was still unable to see the Pages post type. Before the update there would be a custom post type called pages and now that is gone.
I have attached the screenshot below. Sorry about no including that in the first post. I upgraded both wordpress and SLP at the same time from the previous version.
