Put the following code at the END of the configuration.php file BEFORE the closing ?>

ini_set( ‘display_errors’, true );
error_reporting( E_ALL );

And also you can try following tips too,

1. Check server error logs (not access logs) if you have access to them. (cPanel or other control panels often allow this)
2. Go to Joomla Administration → Global configuration and enable Error Reporting to Maximum, you can also turn on debugging.
3. Check the source of the white page – there might be still some HTML/Errors in the Page Source (Look in your web browser for the “View Source” option)

Hope these helps.

The fix is to add the following views/cart/tmpl/default.php (after line 61)

$document->addScriptDeclaration (”
jQuery(document).ready(function($) {
$(‘a.vm-button-correct’).click(function(event)
{
if( $(‘input#tosAccepted’).is(‘:checked’) )
{
document.checkoutForm.submit();
}
else
{
$(‘a.terms-of-service’).css(‘background-color’, ‘red’);
}
});
});
“);
