How do I remove the Home in the middle column next to the Categories box?
This is called the breadcrumb (think Hansel and Gretel) showing where you are and how to get back to previous locations. You can either turn it off completely or you can turn it off only on the main page.
You can turn it off in admin -> configuration -> layout settings -> Define Breadcrumb Status and set to 0.
To turn it off on the main page only in includes -> templates -> YOUR_TEMPLATE -> templates -> common -> tpl_main_page.php find the following lines of code
PHP Code:
<!-- bof breadcrumb -->
<?php if (DEFINE_BREADCRUMB_STATUS == '1') { ?>
<div id="navBreadCrumb"><?php echo $breadcrumb->trail(BREAD_CRUMBS_SEPARATOR); ?></div>
<?php } ?>
<!-- eof breadcrumb -->
and change to:
PHP Code:
<!-- bof breadcrumb -->
<?php if (DEFINE_BREADCRUMB_STATUS == '1' && ($current_page!='index' || (int)$cPath>0 )) { ?> <div id="navBreadCrumb"><?php echo $breadcrumb->trail(BREAD_CRUMBS_SEPARATOR); ?></div>
<?php } ?>
<!-- eof breadcrumb -->
