I've updated my mediawiki from 1.26.2 to 1.27, the installation process finished ok, but when I try to access I received this error:
Warning: require(/var/app/current/includes/specials/SpecialUserLogin.php): failed to open stream: No such file or directory in /var/app/current/includes/AutoLoader.php on line 81 Fatal error: require(): Failed opening required '/var/app/current/includes/specials/SpecialUserLogin.php' (include_path='/var/app/current/vendor/pear/pear_exception:/var/app/current/vendor/pear/console_getopt:/var/app/current/vendor/pear/pear-core-minimal/src:/var/app/current/vendor/pear/mail_mime:/var/app/current/vendor/pear/mail_mime-decode:/var/app/current/vendor/pear/net_socket:/var/app/current/vendor/pear/net_smtp:/var/app/current/vendor/pear/mail:.:/usr/share/pear:/usr/share/php') in /var/app/current/includes/AutoLoader.php on line 81
I have no idea why is this happening. If I check the files in my server they're there. I'm also having template issues if I choose vector I only get a messed up template, without styling.
I'm using PHP 5.6.
I hope someone can help me.
