I haven't changed my username or password recently.
Username and password were unrecognized, so I installed the reset.php in my ndxz-studio/ folder.
I went to site/ndxz-studio/reset.php, it said "Looks OK."
I went to the login and index1/exhibit didn't work. I tried my original login and it still didn't work.
I don't know whether the reset worked and there's something wrong with my browsers (I'm on a Mac, using both Firefox and Safari, same problem in both) or whether there's something wrong with my site.
