Username has spaces

Hi @noblesoft,
WordPress allows whitespaces in usernames, but I see your point. We will remove every whitespace in the next version.

If you need instant solution:

• Open wp-content/plugins/nextend-facebook-connect/includes/provider.php
• Add this line to the right place: $username = preg_replace('/\s+/', '', $username);

    protected function register($providerID, $access_token, $email, $name = '', $first_name = '', $last_name = '') {

        $username = strtolower($first_name . $last_name);
        if (empty($username)) {
            $username = strtolower($name);
        }

        $username = preg_replace('/\s+/', '', $username);

        $sanitized_user_login = sanitize_user($this->settings->get('user_prefix') . $username, true);
        if (empty($username) || !validate_username($sanitized_user_login)) {
