Hello,
I found an error on the website login (using Safari).
=> go to LOG IN / REGISTER and push “LOGIN” (you forgot to fill the username and password fields)
Then, you are in a kind of corrupted state of the authentication system and connot even try to log in again.
phpCAS error: phpCAS::forceAuthentication(): Session should only be renamed after successfull authentication in /var/www/html/wp-content/plugins/cas-authentication/cas-authentication.php on line 142
[solution: quit and restart Safari]
Jean
