TOPIC: [SOLVED] "error: Call to undefined function json_decode()"

Hi

I am working on a site for a client who is using DT Register. I am preparing to upgrade the site from Joomla Version 1.5.14 to Joomla 1.5.23. But before I do the upgrade I am checking to see if all of the extensions are working.

They are using a licensed copy of DT Register 2.7.3a.

PHP version 5.1.6

Here's my problem. When I log into the Joomla administration panel and click on any DT Register item (Categories, Configuration, etc", I get a blank page and this error:

I did a google search and a forum search on this error and didn't find anything specific to DT Register.

Any suggestions to fixing this problem?

Thanks!

You need JSON support in your PHP configuration. Get this enabled... ask your host for help if needed.

And while you're at it... upgrade to the latest DT Register!!

Thank you. Now I know what to fix!

(And yes they'll do the upgrade.)
