Hi Thor,

At my work we has the same problem with member login forms in IE 11, in another .NET based CMS. The solution we have used, is create a  browser file for IE11.browser and drop it the i "App_Browsers" folder.

The file has this content:

<browsers>
    <browser id="IE11" parentID="Mozilla">
        <identification>
            <userAgent match="Trident\/7.0; rv:(?'version'(?'major'\d+)(\.(?'minor'\d+)?)(?'letters'\w*))(?'extra'[^)]*)" />
            <userAgent nonMatch="IEMobile" />
        </identification>

        <capture>
            <userAgent match="Trident/(?'layoutVersion'\d+)" />
        </capture>

        <capabilities>
            <capability name="browser"              value="IE" />
            <capability name="layoutEngine"         value="Trident" />
            <capability name="layoutEngineVersion"  value="${layoutVersion}" />
            <capability name="extra"                value="${extra}" />
            <capability name="isColor"              value="true" />
            <capability name="letters"              value="${letters}" />
            <capability name="majorversion"         value="${major}" />
            <capability name="minorversion"         value="${minor}" />
            <capability name="screenBitDepth"       value="8" />
            <capability name="type"                 value="IE${major}" />
            <capability name="version"              value="${version}" />
        </capabilities>
    </browser>

    <!-- Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11,0) like Gecko -->
    <browser id="IE110" parentID="IE11">
        <identification>
            <capability name="majorversion" match="11" />
        </identification>

        <capabilities>
            <capability name="ecmascriptversion"    value="3.0" />
            <capability name="jscriptversion"       value="5.6" />
            <capability name="javascript"           value="true" />
            <capability name="javascriptversion"    value="1.5" />
            <capability name="msdomversion"         value="${majorversion}.${minorversion}" />
            <capability name="w3cdomversion"        value="1.0" />
            <capability name="ExchangeOmaSupported" value="true" />
            <capability name="activexcontrols"      value="true" />
            <capability name="backgroundsounds"     value="true" />
            <capability name="cookies"              value="true" />
            <capability name="frames"               value="true" />
            <capability name="javaapplets"          value="true" />
            <capability name="supportsCallback"     value="true" />
            <capability name="supportsFileUpload"   value="true" />
            <capability name="supportsMultilineTextBoxDisplay" value="true" />
            <capability name="supportsMaintainScrollPositionOnPostback" value="true" />
            <capability name="supportsVCard"        value="true" />
            <capability name="supportsXmlHttp"      value="true" />
            <capability name="tables"               value="true" />
            <capability name="supportsAccessKeyAttribute"    value="true" />
            <capability name="tagwriter"            value="System.Web.UI.HtmlTextWriter" />
            <capability name="vbscript"             value="true" />
        </capabilities>
    </browser>
</browsers>

And I named the file: ie11.browser. To ensure that the content of "App_Browsers" folder is being re-compilet, you can start by deleting it, make IIS reset after that put the files back + make a new IIS reset.

Perhaps this approach also works in Umbraco, you could give it a try.

Hope this helps.
