Hi to all.
I'm using xampp 1.7 on windows XP. The problem is that there's no fields below the table in http://localhost/security that lists my configuration as unsecure. At first I thought it was a browser problem, but it is not (I tried different browsers). I had already used xampp on Linux and I remember well that passwords could be changed that way (there was also a script, which I don't find for Windows).
I've tried reinstalling XAMPP, but the problem persists.
I couldn't find this topic in the forum: It seems that one can always set the security in http://localhost/security !
Thanks to all.
