Fatal error post.php help :(

by

I would really appreciate any help with my website that crashed and the following error appears

Fatal error: Call to undefined function is_user_logged_in() in /home1/zesiku/public_html/wp-includes/post.php on line 2160″

I have checked cpanel and see the following. The line that says if ( 'readable' == $perm && is_user_logged_in() ) { is the 2160. What to do :(((

function _count_posts_cache_key( $type="post", $perm = '' ) {
    $cache_key = 'posts-' . $type;
    if ( 'readable' == $perm && is_user_logged_in() ) {
        $post_type_object = get_post_type_object( $type );
        if ( $post_type_object && ! current_user_can( $post_type_object->cap->read_private_posts ) ) {
            $cache_key .= '_' . $perm . '_' . get_current_user_id();
        }
    }
    return $cache_key;
}

Put your code in whatever function:

function whatever(){
    // do stuff
}
add_action( 'init', 'whatever' );

Or use this to check whether user is logged in or not:

if( get_current_user_id() ) {
    // logged in user
}
