When i try to debug member.php with zend eclipse studio. It takes me to zend optimizer not installed page. All this fails fails when it tries to load rconfig-zend.inc.php-bin file. I ran tester.php and it says zend optimizer installed. info.php also says zend optimizer is installed. If I disable the debugger every thing works fine. I have latest version of zend optimizer and debugger. My version of amember Pro is 3.0.8PRO, I have to use this verion becaus there is bunch of customization we did to code base. The reason i am using zend otpmizer is because ioncube does not work, it says my files are corrupt and i have checked thousand times to make sure they are not and downloaded it from server using binary transfer. FYI: All this setup is on localhost Any help would be appriciated.
