Hi,

I downloaded the event calender module from the site http://eventcalendar.bluehousegroup.com/ and then placed it in the home directory and builded the database. After this when I try to access the admin page, I am getting website error. Can anyone let me know how I can find out what is the problem and set it right.

TIA
srd

This is the error

[User Error] DataObjectDecorator->setOwner(): Trying to decorate an object of class 'CMSMain' with 'CalendarScriptInit', only Dataobject subclasses are supported.

Hi SRD.
Exactly same problem, with SilverStripe version 2.4. What is a little strange is, that in the backend other sections work fine, only content management section doesn't. When you put ...com/admin/assets/ (for example) to admin access, it opens. but when you try to go site content section of backend, appears error message. By the way, I didn't got clear about that occurred error: have you any glue what it might be and how to arrange it properly?
