我试过禁用APC、Memcached和Varnish，但这没有什么区别。还检查了权限，但似乎所有内容都安装正确

还尝试了通过Magento Connect进行安装，并完成了手动安装，但仍然没有乐趣

有什么想法吗？ 干杯 史蒂夫

打开页面：

包括\src\Mage\u Index\u Model\u Process.php

在函数“public function getIndexer（）”中，找到以下行：

Mage::throwException(Mage::helper('index')->__('Indexer model is not defined.')); 

将此调试行添加到该行之前：

echo $code;exit;

然后再次尝试访问索引页。这应该向您显示产生问题的模块或原因。特别注意您最近安装的扩展（Magento的Activo高级搜索扩展）
