[solved] json error with zencart 1.5 eventhough json installed

[bangsters]

Hi. I have a client that upgraded to zencart 1.5. In Admin login, he gets a blank page, and the debug error shows:

[29-Feb-2012 11:06:53] PHP Fatal error: Call to undefined function json_encode() in /home/domain/domain.com/html/admin/includes/init_includes/init_admin_history.php on line 34


Hi. I have checked my /etc/php.d/json.ini and have this: extension=json.so

I also checked my php compile settings and I have json in there.

Older versions of zencart appear to be working fine.

I'm running PHP 5.2.17 on litespeed

Please advice.

Thank you
