Cannot access Template Style settings [SOLVED]

Hi,

I have just installed gaming Zone with Joomla 2.5 Hotstart on my local lest server. (Cent OS where I have many test Joomla installs)

Template has installed with all the sample data but when i go to access template style setting the page partially loads as per the attachment. I can access settings for other templates OK.

I am also about to install on a hosting that I have to see if the result is the same.

If I view the code I see the following:

<script type="text/javascript">
Joomla.submitbutton = function(task)
{
if (task == 'style.cancel' || document.formvalidator.isValid(document.id('style-form'))) {
Joomla.submitform(task, document.getElementById('style-form'));
}
}
</script>

<form action="/ess-fds/administrator/index.php?option=com_templates&amp;layout=edit&amp;id=14" method="post" name="adminForm" id="style-form" class="form-validate">
<div class="width-60 fltlft">
<fieldset class="adminform">
<legend>Details</legend>
<ul class="adminformlist">

<li><label id="jform_home-lbl" for="jform_home" class="hasTip" title="Default::If the multilingual functionality is not implemented, please limit your choice between &lt;b&gt;No&lt;/b&gt; and &lt;b&gt;All&lt;/b&gt;.

I installed on an external hosting and it works OK, I am guessing as the Template Style settings are complex for this template that my test server is missing perhaps some PHP element

Can you advise if the Template Style needs something particular to be installed as I want to ensure I can use my local test server.

Thanks

I found the error - after checking system error logs - I saw an error PHP Fatal error: Class 'DOMDocument' so I had to install PHP-XML for PHP XML Support
