Getting an error similar to the following when doing a branch or commit in SVN?
svn: Commit failed (details follow):
svn: MKACTIVITY of '/svn/forms/!svn/act/ebcddac9-12da-4ae4-86d8-bdcfbccdc682': 403 Forbidden
Check the case! In this instance, the svn repo was actually called "Forms." Changing the case got rid of the error.
