Installation gone wrong

[wmdvanzyl]

Hi All.

Tried to deploy a finished site to a live server, but instead got this error message:

Fatal error: Call to undefined method Smarty_CMS::registerPlugin() in /home/hummcmgt/public_html/modules/AdvancedContent/AdvancedContent.module.php on line 45

Any ideas? Both the front- and back-end is inaccessible. This is using 1.10.3.

EDIT** I've done a fresh install of 1.10.3 and installing Advanced Content from the Modules Manager breaks the site. Does anyone else experience this. I can reproduce it every time.

PHP versions the same for both servers? I keep on running into issues because my site is still running 5.2
