我所做的唯一变化是将我的sql页面上的连接字符串从本地更改为我的主机服务器指定的字符串.任何提示我可以做什么来找出这个问题的根源？

这里是我的常见问题页面的来源：

我在另一个论坛上发现了这个link：

Well,it appears it’s a bit of both. The message is generated by Firefox,but caused by the framework. For some reason,.NET generates a response type of “application/xml” when it creates an empty page. Firefox parses the file as XML and finding no root element,spits out the error message.

IE不渲染页面,期间.这就是XML来自的地方.

这里是constructFaqSideMenu()函数：

Public Shared Function constructFaqSideMenu(ByVal oSelID As Integer) As String
    Dim oCatList As New List(Of faqCategory)
    Dim oRet As New StringBuilder
    Dim iterate As Integer = 1,extraTag As String = ""

    oCatList = sqlStuff.getFaqCats

    oRet.AppendFormattedLine("<ul id={0}>",addQuotes("submenu"))
    oRet.AppendFormattedLine("    <li id={0}>FAQ Categories</li>",addQuotes("title"))
    For Each category As faqCategory In oCatList
        If iterate = oSelID Then
            extraTag = String.Format(" id={0}",addQuotes("active"))
        Else
            extraTag = ""
        End If
        oRet.AppendFormattedLine("    <li{0}><a href={1}>{2}</a></li>",extraTag,addQuotes("faq.aspx?cid={0}",StrConv(category.Title,VbStrConv.ProperCase))
        iterate += 1
    Next
    oRet.AppendLine("</ul>")

    Return oRet.ToString
End Function
