Do you support Zend Optimizer?

Zend Optimizer, which is software to optimise and protect your PHP by encoding it into a machine readable format, is available to use on our servers. 

However, we do not support the optimised code directly. Once you use Zend Optimizer on your code, you will need to support that code yourself.

Occasionally, you can get an error about it when you run your PHP scripts.

This can happen because you have placed a php.ini (or php4.ini) file in the same directory as the script.  This disrupts Zend Optimizer and prevents it from running.

If you move the php.ini file from the directory into your root directory (above the public_html directory), your script will be able to function correctly and pick up the Zend module.
