The website was upgraded on cloud. The website was totally empty before the upgrade.
I deleted the dev environment, then recreated it. Still now luck.
Using Umbraco 8.6.1 on Umbraco Cloud. I installed the package via the backoffice.
I get the following error when I visit the site AND when I click on the backoffice nodes:
[MissingMethodException: Method not found: 'Umbraco.Core.Models.PublishedContent.PublishedContentType Umbraco.Core.Models.PublishedContent.IPublishedElement.get_ContentType()'.] Umbraco.ModelsBuilder.Umbraco.PureLiveModelFactory.CreateModel(IPublishedElement element) +0 Umbraco.Core.Models.PublishedContent.PublishedContentExtensionsForModels.CreateModel(IPublishedContent content) +64 Umbraco.Web.PublishedCache.NuCache.ContentNode.GetModel(IPublishedContent& model, ContentData contentData) +101 Umbraco.Web.PublishedCache.NuCache.<>c.<HasContent>b__25_0(ContentNode x) +14 System.Linq.Enumerable.Any(IEnumerable1 source, Func2 predicate) +140 Umbraco.Web.PublishedCache.NuCache.ContentCache.HasContent(Boolean preview) +124 Umbraco.Web.PublishedCache.PublishedCacheBase.HasContent() +14 Umbraco.Web.UmbracoInjectedModule.EnsureHasContent(UmbracoContext context, HttpContextBase httpContext) +33 Umbraco.Web.UmbracoInjectedModule.EnsureUmbracoRoutablePage(UmbracoContext context, HttpContextBase httpContext) +94 Umbraco.Web.UmbracoInjectedModule.ProcessRequest(HttpContextBase httpContext) +181 Umbraco.Web.UmbracoInjectedModule.<Init>b__18_4(Object sender, EventArgs e) +80 System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +201 System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step) +132 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +73
