Hi guys,

I am trying to install Merchello (latest version) on fresh umbraco installation (7.4.1).

After installed, both Merchello and FastTrack, the following error is being thrown when accessing the store:

Cannot bind source type System.String to model type Merchello.Web.Models.VirtualContent.IProductContent.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: Umbraco.Web.Mvc.ModelBindingException: Cannot bind source type System.String to model type Merchello.Web.Models.VirtualContent.IProductContent.

Source Error: 


Line 110:
Line 111:            // fail
Line 112:            throw new ModelBindingException(string.Format("Cannot bind source type {0} to model type {1}.",
Line 113:                sourceType, modelType));
Line 114:        }

Source File: C:\Users\Dev5\Downloads\Umbraco-CMS-release-7.4.1\src\Umbraco.Web\Mvc\RenderModelBinder.cs    Line: 112
