Block posts by default

Not sure what you mean by “not working”

Just to manage expectations here, the plugin blocks content, not post titles, etc; the intention being to allow teaser content to encourage registration.

This relies on using the ‘more’ tag in content or the autoexcerpt feature so that post content has an excerpt – otherwise full post content will show on summary pages such as archives or categories.

I would recommend going through the Quick Start Guide to get you started.
