CAPITALIZED words refer to a folder or language that you choose. We use CUSTOM for your template and ENGLISH for your language by default. These generic terms should be changed to the name of the template/language you are using.
If you don't want or need a logo, open includes/templates/template_default/common/ tpl_header.php find and comment out this line of code by adding “<!--” at the beginning, “-->” at the end and “//” between the words php and echo, as shown below.
<!-- <div id="logo">
<?php // echo '<a href="' . HTTP_SERVER . DIR_WS_CATALOG . '">' . zen_image($template->get_template_dir(HEADER_LOGO_IMAGE, DIR_WS_TEMPLATE, $current_page_base,'images'). '/' . HEADER_LOGO_IMAGE, HEADER_ALT_TEXT) . '</a>'; ?>
Save the file to includes/templates/CUSTOM/common/ tpl_header.php and upload it to your server.
