Hi,

I had this before. It was because of a duplicate datatype.

THis post helped me : https://our.umbraco.com/forum/using-umbraco-and-getting-started/109541-throws-an-error-while-adding-a-property-in-a-document-type#comment-344355

I just put in a view of my homepage and then try to view that.

I had a duplicate form picker.

@Tom You can run the following query on your SQL Server. If it doesn't return any data, try adjusting the query to identify any missing information in the tables you're querying. This is the same query Umbraco uses to retrieve content.

SELECT TOP 1 [umbracoDocument].[nodeId] AS [NodeId], [umbracoDocument].[published] AS [Published], [umbracoDocument].[edited] AS [Edited], [umbracoContent].[nodeId] AS [ContentDto__NodeId], [umbracoContent].[contentTypeId] AS [ContentDto__ContentTypeId],[umbracoNode].[id] AS [ContentDto__NodeDto__NodeId], [umbracoNode].[uniqueId] AS [ContentDto__NodeDto__UniqueId], [umbracoNode].[parentId] AS [ContentDto__NodeDto__ParentId], [umbracoNode].[level] AS [ContentDto__NodeDto__Level], [umbracoNode].[path] AS [ContentDto__NodeDto__Path], [umbracoNode].[sortOrder] AS [ContentDto__NodeDto__SortOrder], [umbracoNode].[trashed] AS [ContentDto__NodeDto__Trashed], [umbracoNode].[nodeUser] AS [ContentDto__NodeDto__UserId], [umbracoNode].[text] AS [ContentDto__NodeDto__Text], [umbracoNode].[nodeObjectType] AS [ContentDto__NodeDto__NodeObjectType], [umbracoNode].[createDate] AS [ContentDto__NodeDto__CreateDate], [umbracoDocumentVersion].[id] AS [DocumentVersionDto__Id], [umbracoDocumentVersion].[templateId] AS [DocumentVersionDto__TemplateId], [umbracoDocumentVersion].[published] AS [DocumentVersionDto__Published],[umbracoContentVersion].[id] AS [DocumentVersionDto__ContentVersionDto__Id], [umbracoContentVersion].[nodeId] AS [DocumentVersionDto__ContentVersionDto__NodeId], [umbracoContentVersion].[versionDate] AS [DocumentVersionDto__ContentVersionDto__VersionDate], [umbracoContentVersion].[userId] AS [DocumentVersionDto__ContentVersionDto__UserId], [umbracoContentVersion].[current] AS [DocumentVersionDto__ContentVersionDto__Current], [umbracoContentVersion].[text] AS [DocumentVersionDto__ContentVersionDto__Text], [umbracoContentVersion].[preventCleanup] AS [DocumentVersionDto__ContentVersionDto__PreventCleanup], [pdv].[id] AS [PublishedVersionDto__Id], [pdv].[templateId] AS [PublishedVersionDto__TemplateId], [pdv].[published] AS [PublishedVersionDto__Published], [pcv].[id] AS [PublishedVersionDto__ContentVersionDto__Id], [pcv].[nodeId] AS [PublishedVersionDto__ContentVersionDto__NodeId], [pcv].[versionDate] AS [PublishedVersionDto__ContentVersionDto__VersionDate], [pcv].[userId] AS [PublishedVersionDto__ContentVersionDto__UserId], [pcv].[current] AS [PublishedVersionDto__ContentVersionDto__Current], [pcv].[text] AS [PublishedVersionDto__ContentVersionDto__Text], [pcv].[preventCleanup] AS [PublishedVersionDto__ContentVersionDto__PreventCleanup], COALESCE([ccv].[name],[umbracoNode].[text]) AS variantName FROM [umbracoDocument] INNER JOIN [umbracoContent] ON [umbracoDocument].[nodeId] = [umbracoContent].[nodeId] INNER JOIN [umbracoNode] ON [umbracoContent].[nodeId] = [umbracoNode].[id] INNER JOIN [umbracoContentVersion] ON ([umbracoDocument].[nodeId] = [umbracoContentVersion].[nodeId]) INNER JOIN [umbracoDocumentVersion] ON ([umbracoContentVersion].[id] = [umbracoDocumentVersion].[id]) LEFT JOIN [umbracoContentVersion] [pcv] INNER JOIN [umbracoDocumentVersion] [pdv] ON (([pcv].[id] = [pdv].[id]) AND [pdv].[published] = 1) ON ([umbracoDocument].[nodeId] = [pcv].[nodeId]) LEFT JOIN [umbracoContentVersionCultureVariation] [ccv] INNER JOIN [umbracoLanguage] [lang] ON (([ccv].[languageId] = [lang].[id]) AND ([lang].[languageISOCode] = 'en-US')) --Check and provide ISO Code ON ([umbracoContentVersion].[id] = [ccv].[versionId]) WHERE (([umbracoNode].[nodeObjectType] = 'c00ba0e-eaf3-4cff-8a22-41b16d66a972')) --check and provide correct nodeobjecttype AND ([umbracoContentVersion].[current] = True) AND (([umbracoNode].[id] = 1000)) --check and provide node id
