Topic on Extension talk:DonationInterface

Translating the strings has been harrowing. Why are the base strings for country and province names not on translatewiki.net?

I seriously need help in installing this DonationInterface extension. I can't seem to get it work.

This is the process I took:

I downloaded this extension, added it in a folder in /extension/, added this wfLoadExtension( 'DonationInterface' ); in LocalSettings.php. Then added this also $wgPaypalGatewayEnabled = true;

$wgPaypalGatewayAccountInfo = array( 'default' => array( 'AccountEmail' => 'example@gmail.com', ), );

I need help please installing this plugin
