wordpress plugin -> Call to undefined function wp_get_current_user()

Question

I\'m trying to get the current user info in my plugin using the func wp_get_current_user(). But am getting Call to undefined function wp_get_current_user()

Answer 1

After the installation of wp 3.8 I had the same problem with a page I get with ajax. I fixed it with the following code:

if(!function_exists('wp_delete_user')) {
    include(ABSPATH . "wp-admin/includes/user.php.");
}

Apparently the function is moved from pluggable.php to user.php. Still I don't understand why it doesn't work after I included the wp-blog-header.php.
