在 Sitecore 6.5 中尝试将占位符添加到布局时，我收到以下错误消息：

"不允许使用空字符串。<br>参数名称：xml"

知道可能是什么问题吗？以下堆栈跟踪出现在日志中：

我遇到了这个问题，发现问题的根源是 web.config 中的设置InvalidItemNameChars和ItemNameValidation空白。

将值恢复为默认值后，我已删除这些值以导入包含无效字符的包，如下所示，异常停止发生。

<setting name="InvalidItemNameChars" value="\/:?&quot;&lt;>|[]" />

<setting name="ItemNameValidation" value="^[\w\*\$][\w\s\-\$]*(\(\d{1,}\)){0,1}$" />

最常见的是，这与您的语言设置有关。比如说；如果您的用户（通过默认内容语言）设置为以某种语言编辑项目，则您正在编辑的当前项目没有特定于语言的版本。

例如，您正在使用“en”中存在的项目 - 以及您登录的用户；默认为“da-DK”-并且当前项目在“da-DK”中没有版本。

不过，我已经很久没有看到这个错误了，我本以为它已经修复了。

可能根本不是这个问题，但是从您对这个问题的有限信息中很难判断。

查看您的用户设置；此外，如果您的站点定义中定义的任何“ContentLanguage”属性可能不是您所期望的。
