Based on this answer and the answers given here, it's best to use the following code snippets:

For versions of PHP >= 5.4.0, PHP 7:

function register_my_session() {
    if (session_status() == PHP_SESSION_NONE) {
        session_start();
    }
}
add_action('init', 'register_my_session');

For versions of PHP < 5.4.0:

function register_my_session() {
    if(session_id() == '') {
        session_start();
    }
}
add_action('init', 'register_my_session');
