Notice: Undefined property: CsMegaMenu::$_respMenu in /home/ftp/test/modules/csmegamenu/csmegamenu.php on line 1359

    $this->_respMenu .= '<ul>';
            foreach ($children as $child)
                    $this->_getRespCategories((int)$child['id_category'], (int)$id_lang, (int)$child['id_shop']);
            if ($id_category == 1)
            {
                if ($this->isInstalled('csblog') && $this->isEnabled('csblog'))
                {
                    $id_lang = Context::getContext()->language->id;
                    $url = $this->context->link->getModuleLink('csblog', 'categoryPost');
                    $this->_respMenu .= '<li><a href="'.$url.'"><span>'.$this->l('Our Blog').'</span></a></li>';
                }
            }
            $this->_respMenu .= '</ul>';
        }
