I have a weird question... there is a site that has been running for 2 or 3 years without any problem. It is implemented in 7.6.5, but suddenly some pages started to show the null reference exception.

I have this code:

@Model.Content.GetVortoValue("salaPrensaImagenEncabezado")

it returns this: Umbraco.Core.Udi[]

It doesn't show any exception.

But when I change to this:

@Model.Content.GetVortoValue<IPublishedContent>("salaPrensaImagenEncabezado")

or

@Model.Content.GetVortoValue<IPublishedContent>("salaPrensaImagenEncabezado").Url

note: spaces before and after IPulblishedContent are intentionally to be shown. If I remove those spaces the post question hides the casting.

it shows the null reference exception.

It was working prefectly. This property "salaPrensaImagenEncabezado" actually has value.

These make no difference:

<EnablePropertyValueConverters>true</EnablePropertyValueConverters>

or <EnablePropertyValueConverters>false</EnablePropertyValueConverters>

Error seems to be adding the IPublishedContent . Do I need an "using" or something on the top of the file? I have this heading the file:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@using Our.Umbraco.Vorto.Extensions;
@using ContentModels = Umbraco.Web.PublishedContentModels;
@{
    Layout = "Master.cshtml";
}

Thank you very much in advance.
