Hi Eudes and welcome to our :-)

I'm not sure I will be able to provide you with the correct answer - But before anyone can provide some suggestions on what might be wrong you will need to set "customErrors" mode to "off" in the web.config file in the root of your Umbraco project. Then please share what the error message is.

Afterwards you can switch the "customErrors" element back to "remoteOnly". But when developing locally it's a good idea to have it set to "Off" and when deploying to a live site it should be set to "RemoteOnly" for security reasons since exposing potential errors can be a security risk.

I hope this makes sense? :-)

Hi Jan Skovgaard, Thank you I'll modify the file and I refer the question

Hi, Here is the line of the error thank you for helping me manage

Have you got

@using Umbraco.Web.Models

At the top of your view.

Also, check the version of umbraco you are running. That "Related Link" property type, didnt get added until a recent version. So you may need to upgrade your site.

V7.6+ I think...

Hi, I have try to upgrade my site

Download the .zip file for the new version you are upgrading to from https://our.umbraco.com/download

Copy the following folders from inside the .zip file over the existing folders in your site:

/bin /Umbraco /Umbraco_Client

But here is the error that appears

You need to go through ALL the upgrade steps, which differ depending on what version you are upgrading from.

The Umbraco Documentation provides very good info, on what files you may need to move/add/delete, when upgrading.

Ensure you have done all the steps, or start from a "CLEAN" install, if this is just a hobby site, or a new site.

Hi, i'm using this code to manage my menu item :

@inherits UmbracoViewPage

@using Umbraco.Web.Models

@{ IPublishedContent homePage = Umbraco.AssignedContentItem.AncestorOrSelf("home"); IEnumerable

@helper RenderChildren(IEnumerable

@helper RenderPrettyLink(IPublishedContent item) { RelatedLinks relatedLinks = item.GetPropertyValue

if (prettyLink != null)
{
    if (!item.GetPropertyValue<bool>("disableDropdown") && item.Children != null && item.Children.Where(x => x.IsVisible()).Any())
    {
        IEnumerable<IPublishedContent> childItems = item.Children.Where(x => x.IsVisible());
        bool textOnly = item.GetPropertyValue<bool>("textOnlyInNavigation");
        <li class="dropdown">
            <a class="dropdown-toggle @(textOnly ? "textonly" : null)" data-toggle="dropdown" aria-expanded="false" href="@prettyLink.Link">@prettyLink.Caption <span class="caret"></span></a>
            <ul class="dropdown-menu" role="menu">
                <li>
                @RenderChildren(childItems)
                </li>
            </ul>
        </li>
    }
    else
    {
        <li role="presentation"><a href="@prettyLink.Link" target="@(prettyLink.NewWindow ? "_blank" : null)">@prettyLink.Caption</a></li>
    }

}

}

@helper RenderPageLink(IPublishedContent item) { bool isActive = Umbraco.AssignedContentItem.Id == item.Id;

if (!item.GetPropertyValue<bool>("disableDropdown") && item.Children != null && item.Children.Where(x => x.IsVisible()).Any())
{
    IEnumerable<IPublishedContent> childItems = item.Children.Where(x => x.IsVisible());
    bool textOnly = item.GetPropertyValue<bool>("textOnlyInNavigation");
    <li class="dropdown">
        <a class="dropdown-toggle @(textOnly ? "textonly" : null) @(isActive ? "active" : null)" data-toggle="dropdown" aria-expanded="false" href="@item.Url">@item.Name <span class="caret"></span></a>
        <ul class="dropdown-menu" role="menu">
            @RenderChildren(childItems)
        </ul>
    </li>
}
else
{
    <li role="presentation" class="@(isActive ? "active" : null)">
        <a href="@item.Url">@item.Name</a>
    </li>
}

}
