The RSS Feeds area of sitefinity, along with the newsletter and wiki modules are no longer working. The RSS Feed on the website still worked until the other day when the unassigned blog post was published, causing the RSS to not work.
But when trying to access the RSS Feeds area in sitefinity to change the blog settings, it gives an error and does not let me in. I get the same error when trying to access Wiki and Newsletter.
I think it might be something to do with when I upgraded to SP4, in the upgrade instructions it said something about deleting a file so that one of the modules would work... but when trying to delete that file it wouldn't let me.
Can someone please let me know if there is anything I can do to get these areas of sitefinity working again.
