 * Hi favdv,
 * The PHP version of your server is probably out of date.
    Indeed, the PHP documentation
   says that the function exists since version >= 4.3.0 I think that working on 
   an old version of PHP is unsafe. Could you try to update the PHP version of your
   server or ask to your hosting service?
 * Many thanks for your feedback.
 * Best regards

 * Hello,
 * Thanks for the update. I am currently using it locally with WAMP server 2.5, 
   containing PHP: 5.5.12 (for offline dev purposes), so that can’t be the issue.

 * An upgrade was issued to 1.3.1, which seems to have resolved the issue. Will 
   close the ticket. Thanks
