The WP Curtain login button has stopped working. It worked fine this morning, but I have been trying to log in this afternoon and it does nothing at all when I click it. As a result I’m not able to access my website.
If it was working this morning then I am not sure what could have gone wrong. Did you try disabling other plugins and switching to the default theme? If not, you should try that.
Also, the plugin doesn’t block access to the backend area. You should still be able to login at www.yourdomain.com/wp-login.php
