Hmm jest rechecked the upload

$query="
UPDATE {$config['tbprefix']}ShopMembers
SET money=money-'$itemsarray[price]', signature = ''
WHERE uid='$user[U_Number]'
";
$dbh -> do_query($query);


these lines tell the signature field of ShopMembers to be cleared to '' and thats where the signature is now getting pulled from. Please double check the scripts involved for the correct changes Let me know what happens and I will try and get on your server again
