Fatal error: Class 'PDO' not found in /home/.../public_html/drupal/includes/database/database.inc on line 184 Fatal error:

Problem Resolved: I started over from scratch, and this time I paid close attention to the error messages.

I posted a message to the Lunarpages Help Desk:
I attempted to install Drupal today and I got the below error messages. How do I fix these.
1. PHP extensions ***Error
PHP extensions Disabled
Drupal requires you to enable the PHP extensions in the following list (see the system requirements page for more information):

2. pdo ****Error
Database support Disabled
Your web server does not appear to support PDO (PHP Data Objects). Ask your hosting provider if they support the native PDO extension. See the system requirements page for more information.

3. PHP Memory *** Warning
PHP memory limit 8M
Consider increasing your PHP memory limit to 32M to help prevent errors in the installation process. Increase the memory limit by editing the memory_limit parameter in the file /home/balazs2/public_html/php.ini and then restart your web server (or contact your system administrator or hosting provider for assistance). See the Drupal requirements for more information.
Thank you for contacting Lunarpages Internet Solutions & Web Hosting.

The helpful response I got from the Lunarpages Help Desk
1) If you want to enable all disabled function for your account. Please add the following code in your php.ini (this file is not created by default you would need to upload or create it in public_html)
==================
disabled_functions = ""
==================

2.) To enable PDO, please try adding the following lines into your php.ini file which can be located under your public_html folder (this file is not given by default you would need to manually create or upload it).

extension=pdo.so
extension=pdo_sqlite.so
extension=sqlite.so
extension=pdo_mysql.so

3.) Because we use suPHP to parse php files, you have the option of using a custom php.ini file.

You can change the settings for the PHP directives in your php.ini file which can be located under your public_html folder (this file is not given by default you would need to manually create or upload it) by adding the following code:

memory_limit = 32M

You can also create a .htaccess file in the same folder as the php.ini file and place the following code into it:

suPHP_ConfigPath /home/username/public_html/

where "username" is your cPanel username. This will cause the php.ini file to affect all subfolders, unless a php.ini file is in a subfolder, at which point the php.ini in the subfolder takes precedence.

You should only use the settings you need to change in your php.ini.
For the PHP settings you do not have in your php.ini file, PHP will use our default configurations.

problem solved with this solution, thanks.
