I have a mail parsing script that I set up with help. Up until 3 days ago, it was working flawlessly. Now It's throwing an error... Warning: require_once(PEAR.php): failed to open stream: No such file or directory in /usr/share/pear/mimeDecode.php on line 65 Fatal error: require_once(): Failed opening required 'PEAR.php' (include_path='.:/usr/share/pear:/usr/share/php') in /usr/share/pear/mimeDecode.php on line 65 I verified that mimeDecode.php is in fact present in /usr/share/pear. 1. How can I know if all the Pear files are installed? 2. the script is being called from CLI. I know there are different include paths depending on cli or not cli. Where would I check/edit the path, and what should the path say to make sure it includes Pear? Running CentOS 6.4 x32 Apache 2.2.15 PHP 5.3.3
