if (isset($viewing_mode) && $viewing_mode == 'db') {
$db = $checkprivs;
$url_query .= '&goto=db_operations.php';
// Gets the database structure
$sub_part = '_structure';
require('./db_details_db_info.php');
echo "\n";
} else {
require('./server_links.inc.php');
}
line 1241:
if ( empty( $adduser ) && empty( $checkprivs ) ) {
