Blowfish Support On Shared Webhosting

Yii 1.1 Installation and Setup
1

I am currently evaluating the Yii framework for a new web application.

So I installed Yii on my XAMPP 1.8.1, my Ubuntu 12.04.2 LTS,

and the shared web hosting the new application is supposed to run.

All installations work well,

except on the shared webhosting (aplus) the login page of the blog demo shows the following error:

Error 500

This application requires that PHP was compiled with Blowfish support for crypt().

The phpinfo on that hosting shows:

PHP Version 5.2.9

As far as I can see, crypt supports blowfish.

Is there a workaround in Yii or what should I tell the aplus support to do to make it run?

In the mean time I investigated further and found the following in the description of the PHP crypt function:

Note:

As of PHP 5.3.0, PHP contains its own implementation and will use that if the system lacks of support for one or more of the algorithms.

My other working installations already use PHP 5.3 or PHP 5.4 respectively.

So I suppose it would be more appropriate to state that Yii should run on PHP 5.3+.
