PHP Warning: ['xxxx']: Unable to initialize module

Hello, I'm running Linux 7.2 and apache. Also PostgreSQL. After upgrading from 4.0.4 I receive all of these errors and I have no idea what API=xxx means. I followed the instructions for upgrading to 4.2.1 and everything apparently went well, but still have module errors. Also, phpinfo() still echo'es 4.0, but the CLI sys 4.2.1!!?? What gives?? Is there somewhere to download modules from? A separate way to install them? Any help would be appreciated. Thanks. -steve [root@Zeus /root]# php -m Content-type: text/html PHP Warning: imap: Unable to initialize module Module compiled with module API=20001214, debug=0, thread-safety=0 PHP compiled with module API=20020429, debug=0, thread-safety=0 These options need to match in Unknown on line 0 PHP Warning: ldap: Unable to initialize module Module compiled with module API=20001214, debug=0, thread-safety=0 PHP compiled with module API=20020429, debug=0, thread-safety=0 These options need to match in Unknown on line 0 PHP Warning: pgsql: Unable to initialize module Module compiled with module API=20001214, debug=0, thread-safety=0 PHP compiled with module API=20020429, debug=0, thread-safety=0 These options need to match in Unknown on line 0 Running PHP 4.2.1 Zend Engine v1.2.0, Copyright (c) 1998-2002 Zend Technologies [PHP Modules] xml standard sockets session posix pcre mysql ctype [Zend Modules] [root@Zeus /root]#
