Got this several dozen times in my error.log (seems to be for each view of any page). It's in the main and admin folders.
[01-Dec-2005 20:12:59] 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
What is it and how can I fix it?
Thanks for a great script btw..
