CiviCRM Community Forums (archive)

Hi community,

I habed just installed Civicrm 3.1.1 for Drupal 6.15 and the system work as supposed.
I want make a new newsletter template "User-driven message templates" - the link: civicrm/admin/messageTemplates
I clicked on the link [There are no User-driven Message Templates entered. You can add one. = /civicrm/admin/messageTemplates?action=add&reset=1]


I got this error:
Fatal error: Call to undefined function json_encode() in ..../sites/all/modules/civicrm/CRM/Admin/Form/MessageTemplates.php on line 131

I try this on the civicrm demo [http://drupal.demo.civicrm.org] and Message Template work very well.

Please can someone help me to find the json_encode errors?

Cordial thanks for a fast answer.

Pierre
