دوستان محترم
با راهنمائی ساپورت plesk من تونستم مشکل رو حل کنم . جوابیه ساپورت plesk رو اینجا میذارم که اگر همکاران محترم چنین مشکلی داشتند آن را زود حل کنن.

Plesk control panel stopped working after Zend Optimizer installation. What is wrong?
Product versions this article applies to:
Plesk 7 for Windows
Plesk 7.5 for Windows

The matter is that Zend sets a value for php.ini file in registry.

HKEY_LOCAL_MACHINE\SOFTWARE\PHP\IniFilePath=C:\WIN DOWS


Therefore all .php scripts on the server start to use this setting and go to C:\WINDOWS\php.ini file for PHP configuration.

To fix this problem it's necessary to clear value HKEY_LOCAL_MACHINE\SOFTWARE\PHP\IniFilePath. Then all .php scripts will start to use correct .ini files.
