Use of undefined constant MCRYPT_BLOWFISH

apache, mcrypt, php

Solution

No sooner do I speak do I find a solution, heh.

This worked for me: mCrypt not present after Ubuntu upgrade to 13.10

needed to go: sudo php5enmod mcrypt

even though it appeared to already be enabled, that fixed it.

Problem

After reinstalling our server, `MCRYPT` is no longer working and PHP gives the notice Use of undefined constant `MCRYPT_BLOWFISH` (`Apache 2.4`, `PHP 5.5`). php -m returns mcrypt. ``` ls -al /etc/php5/apache2/conf.d/ 20-mcrypt.ini -> ../../mods-available/mcrypt.ini cat /etc/php5/mods-available/mcrypt.ini ; configuration for php MCrypt module extension=mcrypt.so ``` Why is `mcrypt` not recognized? How can I make this work?
