Dear xwiki-community, Thank you for helping me sofar, getting my XWiki up and running. This weekend I noticed that I could not login from my home computer. Here's what I've found out: Loggin in from a computer within the same network works; logging in from a different network fails, resulting in the following error in xwiki.log: 2010-12-06 11:26:24,663 [http://tcs.dcc.ru.nl/xwiki/bin/loginsubmit/XWiki/XWikiLogin] WARN xwiki.MyPersistentLoginManager - Login cookie validation hash mismatch! Cookies have been tampered with I have the following authentication settings in my xwiki.cfg: xwiki.authentication.validationKey=<set to random string> xwiki.authentication.encryptionKey=<set to random string> xwiki.authentication.cookiepath=/xwiki xwiki.authentication.logoutpage=(/|/[^/]+/|/wiki/[^/]+/)logout/* xwiki.authentication.unauthorized_code=200 I'm running XWiki 2.6 on Tomcat6. Thanks for the help. Best wishes, Mark -- View this message in context: http://xwiki.475771.n2.nabble.com/WARN-xwiki-MyPersistentLoginManager-Login-...
