When front_end_layout is set, it overrides RequestHandler's setting of the layout to 'ajax' if it is loaded via an Ajax request.
I could not figure out why all of my /users/ pages had the default layout, even when loaded via an ajax overlay. I turned out it was because I set the front_end_layout setting to 'default'.
How can I utilize the 'default' layout for normal requests, and the 'ajax' layout for ajax requests, without modifying Spark Plug's internal code? That is how the rest of my site works, but I can't figure out how to use the same thing for Spark Plug.
Thanks.
