Hi,
Thanks, it's working better.
I put some debug traces and I was able to see the problem in the algorithm of the plugin.
Because the plugin was not made originally by the HIkaShop team.
For several shipping methods We can't have test account.. Mostly because we are not based on the US.. So USPS, UPS or Fedex are shipping system were we are not able to deal with, due to some lack of documentation or test account.
I found some issues in the original plugin and we will see to rewrite a part of that plugin.
For the moment I edited you the plugin and just remove (comment) that block of code
if(empty($usps_rates)) {
$app = JFactory::getApplication();
$app->enqueueMessage( 'Failed to obtain shipping quotes.') ;
$responseError = true;
}
