When I go to :
Setup section > Overview > New server button > Configuration Storage
I add an user, a password and a database name (e.g. phpmyadmin) and I submit. I have this message :
Fatal error: Class 'PMA_DatabaseInterface' not found in /var/www/pma/libraries/config/Validator.class.php on line 227
After, from the overview section, I try to edit but I've got the same error.
Thanks for helping ;)
