I have upgraded a project from 3.0 to the latest version, including the blog module and its widgets. Everything works great except a weird rendering of the RSS Feed. It appears to show the actual source code. If I look at e.g. www.silverstripe.org/blog/rss I will see the line of "This XML file does not appear to have any style information associated with it. The document tree is shown below." and then the content in XML tags. With my project however the first line is missing and alls quotes and specialchars are crooked (see attachment). Even if I remove the actual content from the template, to make sure it's not the German spechialchars that cause the problem, it is not recognized as an XML output. I had the same issue with 3.0 which was one of the reasons to upgrade.
Has anyone has this issue before? Any ideas?
Thanks,
Samy
