在注册表中找不到Zend插件Word_CamelCaseToDash

互联网上有很多这样的话题，但因为我不知道该怎么回答，我必须再问一遍。我正在将网站从一台服务器转移到另一台服务器，转移后我看到：

exception 'Zend_Loader_PluginLoader_Exception' with message 'Plugin by name 'Word_CamelCaseToDash' was not found in the registry; used paths:
Zend_Filter_: Zend/Filter/' in /library/Zend/Loader/PluginLoader.php:412

老实说，我没有Zend的技能，所以如果有人能告诉我它出了什么问题？（网站工作人员在以前的主机上没有问题）。
