Yes, I installed it using Simple Scripts through hostmonster. They assigned an admin password. When I went through the Zenphoto application to set up the site, I got to the login page. I logged in as admin and used the password provided by simple scripts. That worked fine. Once at the options page in the admin dashboard, I tried to change the password I was assigned.
Once I changed the password on the dashboard page, that's when I ended up in the endless loop of trying to reset the password. The dashboard would register it had been saved and updated, but when I would logout and try to login again using the new password it kicked me back to the "reset password" loop. At that point, even the previously working password (from Simple Scripts) wouldn't let me login. That's when I reinstalled, and tried adding another admin user, with the same results.
Does that make more sense? I think the problem lies within the password changing page, but I'm not sure how to fix it. Thanks.
