Registration page won't open

First, under Settings → General make sure you’ve checked the box Anyone can register.

WordPress Codex: Settings General Screen

Once your site allows anyone to register, new users should be able to click the “Register” link on the login screen, which would take them to the following url: /wp-login.php?action=register and allow them to register as a new user.

As for moderating newly registered users before allowing them access to your site, I have not built in any moderation functionality to this plugin. This was meant to be a simple plugin only for blocking unregistered users.

How to handle registering new users is up to you. You can either use the built in WordPress controls (no moderation) or add your own custom functionality to include more sophisticated new user registration controls.

Maybe some day I’ll create a new plugin that expands the features of this one and include new user moderation.

Also, make sure you’re using at least version 1.3 of my plugin. I fixed an issue with the new user registration in that release.

Thank you for your reply,I am of course using newest version, and I am using buddypress, maybe there is that problem? Because my registration page is on domain.com/registration (however link on login page points to /wp-login.php?action=register,but it automatically redirects to page /registration)

Ah, you’re using BuddyPress–yes, that is likely why it is not working for you.

The plugin only allows loggedout visitors to view the WordPress login screen and any of it’s variations for retrieving a lost password or registering a new user. Everything else gets redirected back to the login screen.

At the moment, I suppose the plugin doesn’t fully support BuddyPress.

Allright. I suppose there isn’t easy way to add this page? And buddypress uses one more page for activation of accounts,but they need to be created by user as empty pages. So best will be some interface to add exceptions. However thanks for awesome plugin:)
