Hi There,
We guess the issue you have faced, that is your hosting server issue. In this issue, you could contact with your hosting provider. This is because, we have double checked everything and there is no problem in our side.
Please Note: PHPMailer is a 3rd party script. If your hosting server is not supporting this anyway, then there is nothing to do.
Hope you understand.
Best Regards,
ThemeLooks Support Team
