Hi.

Iwe tried to figure out why the "publish at" dont works in my umbraco version, and found this in my umbracoLog table, every time an item should have been published:

Error publishing node: System.NullReferenceException: Object reference not set to an instance of an object.     at umbraco.presentation.UmbracoContext.get_Current()     at umbraco.library.GetXmlNodeById(String id)     at UmbracoExamine.ContentExtensions.ToXDocument(Content node, Boolean cacheOnly)     at UmbracoExamine.UmbracoEventManager.content_AfterUpdateDocumentCache(Document sender, DocumentCacheEventArgs e)     at umbraco.content.DocumentCacheEventHandler.Invoke(Document sender, DocumentCacheEventArgs e)     at umbraco.content.UpdateDocumentCache(Document d)     at umbraco.library.UpdateDocumentCache(Int32 DocumentId)     at umbraco.presentation.publishingService.CheckPublishing(Object sender)

when i press save, the node get's its "unpublish" icon, and after the "publish at" time has expired the node looks like its published, and the "last edit at" is changed to my "publish at" time.

its an 4.0.X upgraded to 4.7.0, i cant say if it has worked before the upgrade.

Can any one help me out here ?

Thx in advance
