Pay Per View Plugin not working

This plugin doesn’t seem to be working out of the box with my theme setup.

After activating the plugin and enabling it on all posts, I didn’t see any change on my site (tried clearing cache). I tested by explicitly enabling pay per view for the following post and still nothing:

Note that I have the setting for Admins to not see full content configured in your plugin.

Also, I receive the following error when editing a blog post:

Failed to load plugin url:

Note that I have the WPBakery Page Builder plugin installed, and I tried disabling the Gutenberg Editor via this plugin’s settings. This caused the error message I mentioned above to go away, but pay per view still didn’t work. I re-enabled the Gutenberg Editor, so u can see the error message on the post mentioned.

Lastly, I’m in Coming Soon mode, not sure if that has to do with anything. You have been granted access to my dashboard.
