Hi i make a fresh installation with php 5.6, i cannot access on my wiki or register new user i get this error:
Fatal error: Class 'MediaWiki\Session\UnexpectedValueException' not found in /membri2/selven/includes/session/Session.php on line 426
here the wiki:
http://selven.altervista.org/index.php?title=Main_Page
it's installed on php 5.6
The "class not found" error is because a patch was not backported to 1.27 before the release. It should be included in 1.27.1, for now you can manually apply this patch.
The error itself is presumably due to your php openssl or mcrypt extension lacking the appropriate mode for some reason; this too will be fixed by that patch.
this has worked and login now work, tomorrow i try the user registration, thankyou
