This plugin has been the best way to do what it does for several years, and I rely on it for the structure of a couple of sites. It does not deserve a one-star review for it's functionality.
The problem is that the current version does not function. When freshly installed, the current plugin version cannot be activated due to a fatal error. But when updating an active copy of the plugin, it white screens the front and back end of the site. To get it back, the plugin folder must be renamed or removed from the server.
That's unfortunate, but it happens. Everyone makes mistakes. What matters it how they're handled.
The new maintainers of this plugin broke the last update by leaving out a required file. As someone in the support forums pointed out, it can be easily fixed by simply adding this small file back in. But the maintainers themselves have not responded. And have not updated the plugin with this very minor fix. As of the time I write this, it's been nearly a week since the put a site-killing update in the repository, and they've just... left it there.
The thing that's kind of a last straw is that the new code that broke everything is for monetization. Which is fine. People gotta get paid. But I'd expect a developer to be especially careful about updating parts of the code that get them paid, since they require literal buy-in from users. Maybe run a few tests? Keep an eye on the support forums? Make sure the thing that asks the greatest degree of trust isn't the thing blowing everything up? No?
If this is how they handle the monetization code, it makes me think this the actual functional parts of this plugin don't have much of a future. So while I still like this plugin (when it works), I have to give it 1 star as a warning.
