How important is the

admin/includes/functions/general.php

file for this mod to work??

Every time I install this mod on a site, about 4 times now, I get a blank admin login page.
I can only make it work with the standard 1.3.9h general.php file.

I checked the difference between the 2 and there were 2 major areas of change, one is this below, which seems to relate to admin?

/*
function zen_draw_admin_box($zf_header, $zf_content) {
$zp_boxes = '<li class="submenu"><a target="_top" href="' . $zf_header['link'] . '">' . $zf_header['text'] . '</a>';
$zp_boxes .= '<UL>' . "\n";
for ($i=0; $i<sizeof($zf_content); $i++) {
$zp_boxes .= '<li>';
$zp_boxes .= '<a href="' . $zf_content[$i]['link'] . '">' . $zf_content[$i]['text'] . '</a>';
$zp_boxes .= '</li>' . "\n";
}
$zp_boxes .= '</UL>' . "\n";
$zp_boxes .= '</li>' . "\n";
return $zp_boxes;
}
