PHP Warning Zend Optimizer

've been getting this cron error emailed to me every day:

PHP Warning:  Zend Optimizer does not support this version of PHP - please upgrade to the latest version of Zend Optimizer in Unknown on line 0
<font color="red">register_globals is On (warning, you should have this param in Off state, or your site will unsafe)</font> <br /> <font color="red">PHP version too old, please update to PHP 5.2.0 at least</font> <br /> <font color="red">mbstring extension not installed. <b>Warning!</b> Dolphin cannot work without <b>mbstring</b> extension.</font> <br />
Please go to the <br />

and solve the problem.

can someone explain what this means and how i can fix it?

dolphin seems to be up and running well enough to do what i need it to do. so whatever is causing this error i am not aware of and need to figure it out but not sure how because i'm not sure what to be looking into...

so there might be some modules that havent installed properly in the background? i'm not sure.

can someone explain what's going on and what to do about it?? thank

Talk to your host, this is server side. They should take care of it.

ok so i am still getting this error. i contacted my host (godaddy) and they told me to install the new zend optimizer.

which i did.

Zend Optimizer v3.3.9

Zend Optimizer
Optimization Pass 1 enabled
Optimization Pass 2 enabled
Optimization Pass 3 enabled
Optimization Pass 4 enabled
Optimization Pass 9 disabled
Zend Loader enabled

it also shows this in the php info

register_globals Off Off

i am using php5 on the account, and it appears that the register_globals is off, and that i'm using the latest version of zend optimizer.

but i am still getting the cron error emailed to me ! what am i missing here?? i really don't understand what is causing it.

It's not the zend optimizer thats to old. It's PHP. Its reported in the message.  PHP version too old, please update to PHP 5.2.0 at least

my php info says:

PHP Version 5.2.8

... so the error still doesn't make sense :( can't figure it out.

Cron in most cases runs the CLI (command line version) of php which can be a different version from what apache uses. If you have shell access then run php -v from the command line and see what it returns for a version. This may just be a case of multiple versions of php on the server causing problems.
