VirtualPathUtility.ToAppRelative NULL reference exception
In file: Orchard\DisplayManagement\Descriptors\ShapePlacementStrategy\ShapePlacementParsingStrategy.cs
VirtualPathUtility.ToAppRelative(ctx.Path ?? "")
VirtualPathUtility.ToAppRelative("") will throw a parameter null exception... I know its not null but but a empty string "" is not valid. hence the ?? "" is irrelevant
Not sure how the code should work but it could be changed to: VirtualPathUtility.ToAppRelative(ctx.Path ?? "/")
