I cannot get my blocks to render in an EPiServer 7.14 MVC site. I can add them to the ContentArea and they render as expected, but as soon as I publish the page they stop rendering. All that outputs to the page (in both edit mode and when visiting the site as usual) is an empty div with a lot of whitespace. If I add another block to the ContentArea they all render again - until I publish the page.

The block view:

@model SiteApp.Models.Blocks.EntranceBlock


  @Model.EntranceTitle

I am rendering the ContentArea to the page like this:

@Html.PropertyFor(x => x.LinkBlocks)

The BlockController:

public class EntranceBlockController : BlockController
{
    public override ActionResult Index(EntranceBlock currentBlock)
    {
        return PartialView(currentBlock);
    }
}

And finally the BlockData:

[ContentType(DisplayName = "EntranceBlock", GUID = "1ff83501-da2f-45c6-bfcb-b77bbd65246a", Description = "")]
public class EntranceBlock : BlockData
{
    [CultureSpecific(false)]
    [Display(
        Name = "Title",
        Description = "Title of this entrance.",
        GroupName = SystemTabNames.Content,
        Order = 1)]
    public virtual String EntranceTitle { get; set; }
}

Appreciate any and all answers or prods in the right direction.
