My server is running pretty much spot on following the perfect guide for Ubuntu 12.04. My install of ISPConfig is working fine. However, following an apt-get upgrade and a reboot, I'm now getting email notifications every 30 minutes that PHP cannot start the pdo_mysql.so library. Email Message is: Code: Subject: Cron <[email protected] After doing some searching, I did read some people say that a more recent version of php had this kind of bug, but I'm not too sure how to troubleshoot. edited to add: my PHP version: Code: php -v PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626/pdo_mysql.so' - /usr/lib/php5/20090626/pdo_mysql.so: undefined symbol: pdo_parse_params in Unknown on line 0 PHP 5.3.10-1ubuntu3.9 with Suhosin-Patch (cli) (built: Dec 12 2013 04:27:25) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies with XCache v1.3.2, Copyright (c) 2005-2011, by mOo Any suggestions?
