Thanks! Here seems to lie the problems: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/pdo.so' - /usr/lib/php/modules/pdo.so: cannot open shared object file: No such file or directory in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/pdo_mysql.so' - /usr/lib/php/modules/pdo_mysql.so: undefined symbol: pdo_raise_impl_error in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/pdo_pgsql.so' - /usr/lib/php/modules/pdo_pgsql.so: cannot open shared object file: No such file or directory in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/pdo_sqlite.so' - /usr/lib/php/modules/pdo_sqlite.so: undefined symbol: pdo_raise_impl_error in Unknown on line 0 This is strange, because: # ls -lah /usr/lib/php/modules/pdo.so -rwxr-xr-x 1 root root 91K Apr 7 16:03 /usr/lib/php/modules/pdo.so # rpm -qf /usr/lib/php/modules/pdo.so php-pdo-5.1.6-3.el4s1.10 So I did: # rpm -e --nodeps php-pdo php-pgsql # ls -lah /usr/lib/php/modules/pdo.so ls: /usr/lib/php/modules/pdo.so: No such file or directory # yum install php-pdo php-pgsql # ls -lah /usr/lib/php/modules/pdo.so -rwxr-xr-x 1 root root 84K Jul 31 2008 /usr/lib/php/modules/pdo.so # service httpd restart And now it seems to work. There must have been something fishy in the previous rpm installation... Thanks for your help, everyone. Cheers, Peter
