Major errors when attempting to install a fresh SSL certificate

I just finished installing my site (Ubunto 14.04/PHP 7.09/Plesk 12.5). But whenver I try to install the Let’s Encrypt free SSL Cert I get the following error (it also happens when I tried PHP 5.5.9). Please help!

 Let's Encrypt SSL certificate installation failed: Failed letsencrypt execution: Traceback (most recent call last):

Can anyone help please? I’d love to use the free SSL but cannot. I also get this error on a second domain I added to my site. :frowning:

Okay fixed after a re-install of the extension. :slight_smile:
