Hi,
the /templates/*.htt files contain the HTML code and placeholder like {PLACEHOLDER}. The placeholder will be replaced with content by PHP code loacted in the WB /admin folder. Most templates files can be linked to their corresponding PHP file (/admin/xxx/yyy.php) via it´s file name.
Example:The template file
templates/pages_modify.htt is invoked from the WB admin file
/admin/pages/modify.php.
You will find the include statements in the corresponding PHP files. They should look like similar to:
$template->set_file('page', 'pages_modify.htt');
Good luck.
