By default Paypal sets the donations landing page to the language of the account/business owner. However this is not desired when the community being hosted is international and therefor prefers English as the main language.
A solution would be to add a setting to the paypal gateway that allows admins to set a language which can be pushed to paypal by adding a hidden form field to the code. I have currently hard coded mine to english by using the following line in the paypal.php file.
$form->hiddenValues['lc'] = 'US'
