On servers where register_globals in PHP settings is turned off, editing templates from ACP (Admin Control Panel) will not save the changes.
To fix that, in admin/templates.php find:if (isset($HTTP_GET_VARS['template_folder']) || isset($HTTP_POST_VARS['template_folder'])) {
Insert above:if (isset($HTTP_POST_VARS['content'])) {
$content = trim($HTTP_POST_VARS['content']);
}
else {
$content = "";
}
