Hi I just downloaded the latest sources from svn and build a fresh war file. (Version 0.9.1000) Then i tried to create a new XWikiClass using the XWikiClasses page. I chooes FAQs as Webname and FAQ as Class name. I got the error message: HTTP Status 404 - /xwiki/edit/FAQs/FAQClass description The requested resource (/xwiki/edit/FAQs/FAQClass) is not available. Any ideas ? Kind regards André
