Cloning a postpage displays Unexpected Error

badhikari - You can simply add all the custom contents on the postpage, why to clone this? Moreover, the exception is because some components are page specific and work only when they are added to the correct context.

I hope this helps.

Hi badhikari,

Unexpected error may have occurred because the components used on PostPage are page specific (meaning calls objects related to PostPage). Hence copying components on custom pages wont work.

But you can try overriding PostPage following the steps in below link
