I confirm the bug and the previous workaround did NOT solve the problem: "sudo apt-get purge php5-mcrypt && sudo apt-get install php5-mcrypt does not resolve this issue."
This does solved it: Check if mcrypt is not enabled: root@prod:/etc/php5/mods-available# php -m | grep mcrypt Symlinks to the wrong mcrypt.ini as a workaround: root@prod:/etc/php5/mods-available# ln -sf /etc/php5/conf.d/mcrypt.ini . Enabled the mcrypt mod: root@prod:/etc/php5/mods-available# php5enmod mcrypt Check if it was enabled: root@prod:/etc/php5/mods-available# php -m | grep mcrypt mcrypt Restart services: root@prod:/etc/php5/mods-available# service apache2 restart -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1318021 Title: Not Find mcrypt.ini To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php-mcrypt/+bug/1318021/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
