first of all, I'm not that experienced with silverstripe - hope that's alright :)
I set Silverstripe up and installed "image_gallery", "dataobject_manager" and "swfupload". Works fine so far.
When I try to access an image gallery, I recieve an error message: Website Error, There has been an error,
The website server has not been able to respond to your request.
In the dev-mode it reads like this: http://pastebin.com/gbPPYvAp (I replaced the actual website with [ url ]).
Any suggestions? I don't really know how to proceed.
