@foopong, if there’s something specific anyone has trouble with in working with the plugin, we’re happy to assist, as you can see.
Many times, troubles derive from the plugin settings being configured in ways that cause logical issues like a protected page, which is supposed to be the page displayed in place of protected content, being negated by a page rule that restricts access to it.
It could also come down to simple logic issues like category rules and post rules set in positive and negative configurations that end up countering each other.
But that’s why we’re here to walk folks through those types of difficulties. And we’d be happy to help you with any trouble you’re experiencing on that, though if you’re settled with s2member that’s fine.
