yes, works like a charm, to bad your plugin doesn’t work though 🙁
went and used s2members plugin, it worked out of the box…
the server was linux, the same thing happened on my local servers (both linux and win7), the pages were created (invoice, billing info, checkout…) and the content which was tagged as ‘members only’ worked as it suppose to, but when selecting membership levels, it just redirected to that page again and again, never loading the checkout page
