Check if the front end user is log in or not

I am using “front-end-only-users” plugin for user registration and log in system. Now how i check that my front end user is log in or not through coding i use ‘is_user_logged_in()’ but it checking the admin panel user.

write this code in front page to check user is login or not:

 if ( is_user_logged_in() ) { ... }
