Not working

Hi, I tried using this plugin
https://wordpress.org/plugins/easy-member-pro/
but its not working.

I installed the plugin, activated it and did all of the settings. I applied protection to all post globally to test and it did, which was nice. Now users need to register and login to my EMP site to gain access to my WP posts. I registered and logged in to EMP using the plugin’s built-in form, but still cant view any of the protected post. It only shows me “This content is for Havenfo.com members with one of the following memberships.”. I cant find any solution to this.

I tried using this plugin from WordPress 4.2.0 upto latest. Same problem to all versions.

Please assist. Thanks.
