Question : I got this error Log in CMS (Joomla and Wordpress) : PHP Warning: Module ‘PDO’ already loaded in Unknown on line 0.
Solution:
First locate php.ini
Locate php.ini
In VPS and dedicated server with centos installed php.ini should be under /usr/local/lib
Edit php.ini file en remove the extra duplicated lines ,
; If you wish to have an extension loaded automatically, use the following ; syntax: ; extension = "pdo.so" extension = "pdo_sqlite.so" extension = "sqlite.so" extension = "pdo_mysql.so" extension = "pdo.so" extension = "pdo_sqlite.so" extension = "sqlite.so" extension = "pdo_mysql.so" ;
Now restart apache
/etc/init.d/httpd restart
