I believe I have a problem with my theme which causes my WP-ADMIN screen to show nothing but white space. I've tested this on two different installs of WP hosted on different machines and I'm confident it's not a WP problem but something I've done in the process of constructing a Thematic framework child theme.
All the work I've done on the theme is in two areas, my style.css and functions.css. I do not think my style.css file would cause any problems, and an error message displayed by Firefox leads me to believe it's my functions.php file that's the problem.
Here's my functions.php in full:
<?php
function my_scripts() { ?>
<script type="text/javascript">
jQuery.noConflict();
function equalHeight(group) {
tallest = 0;
group.each(function() {
thisHeight = jQuery(this).height();
if(thisHeight > tallest) {
tallest = thisHeight;
}
});
group.height(tallest);
}
jQuery(document).ready(function() {
equalHeight(jQuery("#content,#secondary"));
});
</script>
<?php }
add_action('wp_head','my_scripts');
function add_stuff(){
echo '<div id="header-menu">As Fission Design we are a collective of creative people promoting our work and our creative industry.</div>';
}
add_action('thematic_header','add_stuff',6);
// Remove default Thematic actions
function remove_thematic_actions() {
remove_action('thematic_header','thematic_access',9);
}
add_action('init','remove_thematic_actions');
add_action('thematic_aboveheader','thematic_access',9);
?>This is the error that Firefox returned when I tried my theme on a second WP install. The text was displayed after I logged out of my WP site. The site automatically logged me in, and once I'd changed the theme to the problematic one I logged out to see this:

I've changed the path as it contained my cPanel user name, but otherwise it's as displayed. I apologise if this is a very simple PHP question, but I've a very limited knowledge of the language.
