Sitecore安装失败，从InvalidItemNameChars中删除了值并禁用了ItemNameValidation，但仍然出现错误

Question

我正在尝试在Sitecore 8.0中安装Sitecore Experience Extractor软件包。我不断收到错误消息“项目名称不能包含以下任何字符：/ :?” <> | []-（由InvalidItemNameChars设置控制）。我更新了Web配置，以删除了无效字符：

  <setting name="InvalidItemNameChars" value="" />
  <!--  ITEM NAME VALIDATION
        Regular expression for validating item names
  -->
  <setting name="ItemNameValidation" value="" />
  <!--  ITEM NOT FOUND HANDLER
        Url of page handling 'Item not found' errors
  -->

我还根据这篇文章添加了一个补丁：https://sitecore.stackexchange.com/questions/5503/sitcore-wffm-installation-error-an-item-name-cannot-contain-any-of-the-follow

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <settings>
      <setting name="ItemNameValidation">
        <patch:attribute name="value"></patch:attribute>
      </setting>
    </settings>
  </sitecore>
</configuration>

但是我仍然遇到错误。
