I have installed Zend Optimizer 3.2.2 on my server. After I do so, you can go to any of my websites and the browser will just hourglass. When I restore the original php.ini the sites come back fine. Here is a phpinfo page to see my server. http://www.zycronmail.com/phpinfo.php I cannot figure out what is going wrong...unless I need to recompile something although nothing has said I have to. Thank you for any help.
