When I SSH as root to my server, and do php -m, for Zend Modules it reads:

[Zend Modules]
Zend Extension Manager
Zend Optimizer

But if I SSH as a regular account for one of my domains (jailshell) and type php -m, I get:

[Zend Modules]

Does this mean that Zend Optimizer isn't enabled for any of my clients? Or is this normal? If not, how can I fix this?

TIA.
