My hunch is this has something to do with the fact that this site is still under development and the URL structure is not Live yet.
18.104.22.168/~riteoak/blog/ will eventually have a URL structure something like riteoak.com/blog
When I check your Source Code I do not see a canonical link reference
<link rel="canonical" href="xxxxx" />
which means you are not using a Custom Permalink Structure. BPS requires that you use a Custom Permalink Structure.
You should still be able to use BPS to protect your website while it is under development, but you must be using a Custom Permalink Structure and your WordPress General Settings must be correct:
WordPress Address (URL)
Site Address (URL)
When your site is ready to go Live then you would of course change your General settings.
