Hi,
since Silverstripe 2.4 i have an problem with internal Links in a Newsletter.
I think, that's a effect of the new nested URL's.. I hope you know the real reason and can help me! :)
The Newsletter Modul generate links like this: <a href"=[sitetree_link id=18]">
If i click: Silverstripe call the 404 Page.
(Sorry for my bad english!!!)
Christian :)
