Hi folks,

I have a site set up on Umbraco v8 and we've just noticed a very peculiar bug: if an admin has the Preview mode open in the backoffice, dynamic page URLs are being rendered as '#' even when they're accessing the site in other windows. Since our top menu uses page.URL in order to be dynamic, this means that anyone who's editing the site has severe difficulty also navigating the site unless they exit out of Preview mode first.

Does anyone know what might be causing this?

The code for the dynamic menu section is as follows:

                <li><a href="/">Home</a></li>
                @foreach (var page in Umbraco.ContentAtRoot().FirstOrDefault().Children.Where(x => !x.IsVisible()).OrderBy(x => x.SortOrder))
                {
                    <li class="@(Model.IsAncestorOrSelf(page) ? "active" : null)">
                        <a href="@page.Url">@page.Name</a>
                    </li>
                }

Whether it's all of the page.Urls becoming # or just some of them doesn't seem to be consistent, which is also concerning.
