Is there an id column on the settings row? Is it a single row in the table? Can you do an
PHP Code:
<?php echo $s; ?>
and show us what you're actual query looks like that gets sent?
If there is an id column, I'm pretty sure the settings id would be 1 so...
PHP Code:
$s = "UPDATE settings SET title = '$title', status = '$status', main_logo = '$logo', offline_text = '$offline', logo_left = '$left_logo' WHERE id = '1' ";
