 * The plugin used to work fine, but recently it has failed to download pdf invoices.
   The system keeps loading and loading with no results. I also get a critical error
   when doing a preview.
 * This is the order log:

 * Hello!
 * Do you have an old version of he plugin by any chance? and if so could you update
   and try again? I think that will fix the issue.
 * Regards!
