Is it possible to leave Zend installed and then install Turck MMcache on top? I already have the Zend optimiser installed because we use WHMAutopilot which needs it in order to decode it. I have tried a search but nobody mentioned whther you can do it this way around or not.
Yes, you can have Zend installed first and then install mmcache. But if you ever want to support IONCube, i wouldn't recommend installing it. But if you don't want to support it, then yes its a very good thing to install.
