Hi all, I installed Zend Optimizer and I seemed to have goofed something up in the process: my websites will no longer load. I have Fedora Core 6 with all the latest updates installed, Plesk v8.2.1 and Zend Optimizer v3.3.0. I can log in through SSH, I can get to my Plesk control panel... but I can't get my websites to come back up. What is going on? Two of the websites are running Drupal v5.2 and the third only displays the default Plesk welcome page (nothing special). I used this document to help me install: http://kb.nitix.com/3747 I used all the defaults during install. One thing to note: when the Zend Optimizer installer tried to reboot, it did not work. I went to the Plesk Control Panel to handle that after the fact. I'd also like to note, I'm pretty new to the world of linux so verbose answers help me a little more because I'm not savvy enough to skip steps. More info: When I typed php -v , I got this: This would seem to be the true error... I've killed Sitebuilder and need to do something with Zend Optimizer's ionCube. If you can help and solve these issues, I'll name my first born after you. That's a couple years away, though! Anyhoo, any help would be appreciated!
