[SR-Users] Siremis 3.2.1 PDO Issue.

Hi, I'm installing a brand-new Kamailio / Siremis system. I have an issue with Siremis failing to load PDO extensions. I have other systems working O.K. on Centos 5.x This is my configuration: Centos 6.2 php-5.3.3-3.el6_2.8.i686.rpm php-cli-5.3.3-3.el6_2.8.i686.rpm php-common-5.3.3-3.el6_2.8.i686.rpm php-mysql-5.3.3-3.el6_2.8.i686.rpm php-pdo-5.3.3-3.el6_2.8.i686.rpm Siremis 3.2.1 php -m [PHP Modules] bz2 calendar Core ctype curl date ereg exif fileinfo filter ftp gettext gmp hash iconv json libxml mysql mysqli openssl pcntl pcre PDO pdo_mysql pdo_sqlite Phar readline Reflection session shmop SimpleXML sockets SPL sqlite3 standard tokenizer xml zip zlib [Zend Modules] The area where it screws up is in util.php while I am setting up Siremis via web-page $status[5]['item'] = 'PDO extensions'; $pdos = array(); if (extension_loaded('pdo')) $pdos[] = "pdo"; if (extension_loaded('pdo_mysql')) $pdos[] = "pdo_mysql"; if (extension_loaded('pdo_mssql')) $pdos[] = "pdo_mssql"; if (extension_loaded('pdo_oci')) $pdos[] = "pdo_oci"; if (extension_loaded('pdo_pgsql')) $pdos[] = "pdo_pgsql"; $status[5]['value'] = implode(", ", $pdos); $status[5]['status'] = $pdos[0]=='pdo' ? 'OK' : 'FAIL - PDO extensions are required.'; I have commented out the test but it fails later saying the PDO extensions are not loaded. I note that the php modules report gives upper case but the test is lower case. (I understand the extension_loaded function is case insensitive) Any assistance appreciated.
