Fatal error: Class 'PDO' not found

I have installed a fresh copy of Dolphin 7.3.0 and when I try to install the modules I get an error:

Fatal error: Class 'PDO' not found in /home/.../public_html/modules/boonex/oauth2/classes/BxOAuthModule.php on line 40

Does anyone have had a similar problem? 

I searched and found the following solution online:

PDO support had been compiled in, but not enabled .
Adding
extension=pdo.so
extension=pdo_mysql.so
to my php.ini solved the problem.

then I checked on my server and I see that I have a local php.ini and I actually see

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

already in my php.ini.

I am not sure where to look at and any help would be much appreciated.

Thanks!

Never mind my question. I found the solution. I had an older version of local php.ini. I changed it and the issue is resolved.

Thanks.
