I can find nothing that stands out as being wrong. I'll post some of the code that might be relevant-
includes/modules/sideboxes/categories.php
$check_categories = $db->Execute("select categories_id from " . TABLE_CATEGORIES . " where categories_status=1 limit 1");
if ($check_categories->RecordCount() > 0) {
$box_categories_array = $main_category_tree->zen_category_tree();
}
require($template->get_template_dir('tpl_categories.php',DIR_WS_TEMPLATE, $current_page_base,'sideboxes'). '/tpl_categories.php');
$title = zen_image($template->get_template_dir(BOX_HEADING_CATEGORIES, DIR_WS_TEMPLATE, $current_page_base,'images'). '/' . BOX_HEADING_CATEGORIES, Categories);
$title_link = false;
require($template->get_template_dir($column_box_default, DIR_WS_TEMPLATE, $current_page_base,'common') . '/' . $column_box_default);
?>
includes/templates/pure_orange/common/tpl_box_default_left.php
<!--// bof: <?php echo $box_id; ?> //-->
<div class="leftBoxContainer" id="<?php echo str_replace('_', '-', $box_id ); ?>" style="width: <?php echo $column_width; ?>">
<div class="sidebox-header-left <?php echo $header_left; ?>"><h3 class="leftBoxHeading <?php echo $header_right; ?>" id="<?php echo str_replace('_', '-', $box_id) . 'Heading'; ?>"><?php echo $title; ?></h3></div>
<?php echo $content; ?>
</div>
<!--// eof: <?php echo $box_id; ?> //-->
includes/templates/template_default/templates/tpl_index_categories.php
// categories_image
if ($categories_image = zen_get_categories_image($current_category_id)) {
?>
<div id="categoryImgListing" class="categoryImg"><?php echo zen_image(DIR_WS_IMAGES . $categories_image, '', SUBCATEGORY_IMAGE_TOP_WIDTH, SUBCATEGORY_IMAGE_TOP_HEIGHT); ?></div>
<?php
}
} // categories_image
