I forgot my password, so I entered the captcha and received an email with a link to the admin page. I clicked that and changed the password in the form, but I still couldn't login. So I looked at the DB, and did the operation again -- and the password hash in the DB didn't change. The third time I tried adding a new user, and no new record was created.

There seems to be a bug.

Did the admin pannel say the change was saved? This is not something I can reproduce.

No, when I click "save" I get bounced back to the login screen. Should it stay on the admin screen?

On my admin screen, I have two users listed. The save button is in the space for a third, new, user.

I ran the form post while the firefox live headers extension was active; the post looks like this:http://view.flavor8.com/zp-core/admin.php?page=options&action=saveoptions

Can you please try upgrading to the 1.1.7 release? You should upload the files then drop the administrators table, then run the 1.1.7 setup.

The reset did the trick. FWIW I had to delete from administrators, rather than drop it; when I dropped it, the admin screen wouldn't save. (Luckily I'd backed up.)

Setup should have recreated the administrators table. But no matter. Glad you are in business.

Edit: I have solved the issue follow the link from other post. Thanks anyway!

I have the same problem here!
What is the procedure to make it work?
Any help please? Im new on this...

Same issue here. I'm locked out at this moment in time. Running latest release. Something is not functional.

Edit: I can't access anything right now. I set a password on the gallery and now I can't get into the Admin. It dropped me to the login and I'm locked out now. Password reset sent twice, non functional.

I have no idea or ever noticed this myself but here is a workaround to get back in: http://www.zenphoto.org/2009/03/troubleshooting-zenphoto/#16
