When i try to add a wiki site to my main site, i get an page that says "Error - An Unexpected error has occurred - Troubleshoot issue...". This isn't a particularly helpful error message and i'm slighlty stuch as to how to progress. Has anyone else had this issue, if so how did you solve it?
EDIT --- Thanks @Wictor, i took your advice and hunted through the ULS File, and found four lines that had "Failed" in them
