Answer 1

Found a super simple solution to this in Sitecore 6.6. Just rename the iFrame to div!

      <div id="SDN">
            <div id="StartPage" runat="server" allowtransparency="true" frameborder="0" scrolling="auto"
                marginheight="0" marginwidth="0" style="display: none"></div>
        </div>

Answer 2

Your target framework must be 4.0 in order for Sitecore to work properly. Version 4.5 is not yet supported

Answer 3

First you'll need to find and edit the file default.aspx in Website\\sitecore\\login.

Change this:

<div id="SDN">
    <iframe id="StartPage" runat="server" allowtransparency="true" frameborder="0" scrolling="auto"
                marginheight="0" marginwidth="0" style="display: none"></iframe>
</div>

to this:

<div id="SDN">
    <div id="StartPage>   </div>
</div>

Save this file.

The iframe displays browser compabitibilty information from sitecore on the right side of the login page.

What happens is that when you use .NET 4.5, the iframe compiles to an HtmlIframe control. The code behind file from sitecore however has the iframe as an HtmlGeneric control. Hence the message.

By changing the iframe to a div, ASP.NET will generate an HtmlGeneric from the .aspx page which matches what is in the compiled code behind and the login page is then able to load.

我得到了相同的错误，并在web.config文件中的复杂性条目中添加了“targetFrameowkr = 4.5.1”并修复了问题。

Answer 5

我遇到了同样的问题，并且我已经将web.config文件中的目标框架从4.0更改为4.5。

Answer 6

我找到了解决方案，我只需要自定义登录页面。
