Fatal json error after transferring site

[Mo Raelin]

I have just transferred my fully working Joomla 2.5 site to a new webserver, and I'm getting the following error showing.

Fatal error: Call to undefined function json_decode() in /home/sites/mysite.co.uk/public_html/libraries/joomla/registry/format/json.php on line 67

Can anyone offer any advice on what might be causing this?

Can you still enter the administrator backend? If so, go to Site --> System Information --> PHP information. Search that page for 'json' to check if it is enabled. My guess is that it's not.

I can't access the admin panel Tonie.
Browser just shows the same error.

Is there a file I can download via FTP and edit to enable json??

You can create a file on your workstation with the following code.

<?php
phpinfo();
?>

If you call this file info.php, and copy it to the root of your website (where configuration.php is), call it with http://yourwebsite/info.php. You can then check if it's enabled. It it's not, I'd contact the hoster first as it's a PHP module.

Hi Tomie

I followed your instructions and I have attached the page that I was shown as a screenshot.

Json was only mentioned twice on the page as you can see.

Does this mean it is enabled already??
