Trying hard to get everything working and to solve my own problems by researching but currently I'm really confused.

I can enter guestbook entries and the settings components seem to work ok but when I try to approve or delete an entry I get an error which, despite a lot of forum reading, I still can't find a good solution to.

Any advice (at all) really appreciated - I'm losing a lot of sleep over this one.

DotNetNuke.Services.Exceptions.ModuleLoadException : 'WroxModules.GuestBookCS.EditGuestBookCS' is not allowed here because it does not extend class 'System.Web.UI.UserControl'. ---> System.Web.HttpParseException: 'WroxModules.GuestBookCS.EditGuestBookCS' is not allowed here because it does not extend class 'System.Web.UI.UserControl'. ---> System.Web.HttpParseException: 'WroxModules.GuestBookCS.EditGuestBookCS' is not allowed here because it does not extend class 'System.Web.UI.UserControl'

So after several more hours of stress and confusion I found that this problem had been encountered before and deleting then re-creating the offending files might work. I tried this and not it seems ok.
