Hi Thomas, Thanks for the reply! Yes, the link you provided is the right one with the bug we face. The thing is we may not be able to upgrade to a newer version of XWiki recently, so we plan to add a title for XWikiServerXwiki page as the workaround. Do you think it is safe? And do you have any specific idea why an internal XWiki page exists without a title and how we can prevent this from happening again? Thank you!
