You cannot access the private section of this site

Please I urgently need your support on this issue: Error: You cannot access the private section of this site.

I installed Model Agency on fashion.magxenia.com and after registering, I am unable to login.

I set the Site Login for global configuration and every is intact as default joomla setting. But yet registered users can't login

Please kindly let me know what steps to take to fix the issue of Error: You cannot access the private section of this site on fashion.magxenia.com

It is very urgent.
