Ban ip. problem with sqlite3

Windows:
Go into the php map and look for php.ini (if it dosent exist reame php.ini-development to php.ini)
In php.ini search for dynamic extensions.
Find:
;extension=php_sqlite3.dll and remove ;
do the same thing for:
php_mysql.dll
php_gd2.dll
php_pdo_sqlite.dll
php_sockets.dll
Then you need will have to:
Change display_errors = off to display_errors = on
then change extension_dir to extension_dir = "C:\php\ext" (if you installed it on another place use that 'adress' instead.)
done.

Have i missed something?
