Fatal error!

[shumphreys]

Hi,
having got the new site running fine on a development box, I have just uploaded it to the host and am getting lots of errors/warnings (in DEBUG mode).

The fatal error: Call to undefined method SimpleXMLElement::addChild() is the latest problem when I am tryign to chaneg anything from the admin panel.

SimpleXML is enabled (Revision: 1.151.2.10)on the server (Revision: 1.151.2.22.2.39 on the development box)

I removed all plugins as this was causing errors initially (though I will need to put them back ... permission errors mostly)

Any advice/help ... please ...?

Thanks

Umm ... just seen that the server has PHP 5.1.3, and my development box has PHP 5.2.6 .... I guess that's the problem?
