Unlock Button didn't work on Paused Page?

My page is currently paused, and I’m testing the plugin on my website with the help of my existing patron. Wordpress seems to create their account fine, but they still can’t see the content after using the unlock button.

Any idea where I did it wrong?

Please check out that a cached stale page is not being served to your patron.

You should check your settings at your caching plugin if you use one.
