Hello there, I ran into a problem when trying to create a Block of a certain type.

The exception in my log file is as follows:

2018-09-26 12:47:39.683 +02:00 [Error] Unhandled exception in Website, ExceptionContext: { Url: "http://local.waternet.nl/EPiServer/cms/Stores/contentdata/", UserAgent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36", Method: "POST", StatusCode: 200, Machine: "DESKTOP-5KUFAB8", TrackingCode: "S4CG3" }
System.Data.SqlClient.SqlException (0x80131904): The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tblContent_tblContentType". The conflict occurred in database "Waternet_Global_Epi_Dev", table "dbo.tblContentType", column 'pkID'.

I see the ContentType in the admin view, however, when trying to edit it's settings and saving it, it gives the message, ContentType Deleted, after that it's nowhere to be found anymore. Is there any way this is fixable in the database itself?

Thanks in advance!
