Hi, May I know if PHP in Plesk Windows support PEAR? I checked in phpinfo(), i saw this: include_path .;./includes;./pear .;./includes;./pear But when i enter below code <?php require_once 'System.php'; var_dump(class_exists('System')); ?> It shows: Warning: require_once(System.php) [function.require-once]: failed to open stream: No such file or directory in D:\inetpub\vhosts\oxy.com.my\httpdocs\php\mailtest.php on line 2 Fatal error: require_once() [function.require]: Failed opening required 'System.php' (include_path='.;./includes;./pear') in D:\inetpub\vhosts\oxy.com.my\httpdocs\php\mailtest.php on line 2 I read from another forum, they advice to change the path in php.ini. My current config in php.ini is: ; Windows: "\path1;\path2" ;include_path = ".;c:\php\includes" include_path = ".;./includes;./pear" Please advice. Thanks.
