This worked for me: mCrypt not present after Ubuntu upgrade to 13.10
这对我有用： Ubuntu 升级到 13.10 后不存在 mCrypt
needed to go: sudo php5enmod mcrypt

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

Firstly, we can run this cmd to check the mcryptis running or not:
首先，我们可以运行这个cmd来检查mcrypt是否正在运行：
php --ri mcrypt
If mcryptis not enabled, we can use the following to enable it as others mentioned

sudo php5enmod mcrypt
As well, we had better check php5-mcryptpackage is installed or not
同样，我们最好检查php5-mcrypt软件包是否安装
dpkg -l | grep php5-mcrypt
