I think I can safely rule out browser and server problems, as nothing 
has changed. I also tried it with Opera but had the same problem.

I am using two addons: "titledictindex" and one of my own (not pretty, 
but it works; attached file [codecogs.php]). I've also attached my 

Even when I use a vanilla config (from docs/) and use DefaultPasswords 
it still asks me again and again. Quite puzzling.
