I am working on my PHP file and now I get this message.

"Parse error: syntax error, unexpected '<', expecting T_FUNCTION in /home/content/18/9029618/html/wp-content/themes/NewBusiness/includes/aboutus.php on line 8"

Have no idea what is wrong and now my site is down. Here is the code below.

<?php

new Themater_AboutUs();

class Themater_AboutUs
{
    var $theme;

    var $defaults = array(
        'enabled' => 'true',
        'hook' => 'main_before',
        'title' => 'Welcome to our website. Neque porro quisquam est qui dolorem ipsum dolor.',
        'image' => 'about-image.jpg',
        'content' => 'Lorem ipsum eu usu assum liberavisse, ut munere praesent complectitur mea. Sit an option maiorum principes. Ne per probo magna idque, est veniam exerci appareat no.

    );

    function Themater_AboutUs()
    {
        global $theme;
        $this->theme = $theme;

        if(is_array($this->theme->options['plugins_options']['aboutus']) ) {
            $this->defaults = array_merge($this->defaults, $this->theme->options['plugins_options']['aboutus']);
        }

        if($this->theme->display('aboutus_enabled') ) { 
            $this->theme->add_hook($this->defaults['hook'], array(&$this, 'display_aboutus'));
        }


        if($this->theme->is_admin_user()) {
            $this->aboutus_options();
        }
    }


    function display_aboutus()
    {
        if(is_home()) {
            ?><div class="span-24 aboutusbox">

            }
            ?></div><?php
        }
    }

            array('help' => "Enter the full url. Leave it blank if you don't want to use an image.")

        );
    }

• parsing
• syntax

Is that the full file? Is there a <?php at the beginning?

The sample that you have pasted is missing a closing brace } at the end.
