I have the same problem once every month or so with some of my customers. found various threads, let's consolidate them to the biggest extent:

possible solution (which I, though, do not quite understand as it is pretty technical and I am sure I did neither upgrade PS nor uploaded a database backup):

I have same problem after I upgarde 1.31 to 1.41.
at 1st. I checked the setting.inc.php, there was not mistake. then I try to create new A/C and found the PSW in notic email is very long, not as my type.
Then I think there is problem in code.
so i compared the code of authentication between 1.31 and 1.41 (remark: v1.41 is authcontroller.php),
and found line 77 in authcontroller.php wrote

if (!Tools::getValue('is_new_customer'))
$_POST['passwd'] = md5(time()._COOKIE_KEY_);

change to

if (!Tools::getValue('is_new_customer'))
$_POST['passwd'] = trim($_POST['passwd']);

Now I sloved my problem. I think your problem is similar like mine, different is that you just upgrade to 1.31. I suggest you check it step by step like me.

Just delete the installation folder "Install" inside the prestashop folder. It will work.
