Hi,
sorry for my english.
I try to load files of zenphoto into my website and I set username, password and database without problems. The website is good (ftp, etc.), but I can't open setting of zenphoto (zp-core/admin.php), because the loggin tell me this message: "There was an error logging in. Check your username and password and try again."
How do I set my password to access in setting of zenphoto?
In where files I can find password or setting to set, so I can access?
Thanks.

Sadly this occasionally occurse but we don't know why. The only fix is:

Hello This happened to me.

1. Login to your mySQL client (phpMyAdmin)
2. Select the database of your zenphoto (left side)
3. look for zp_administrators table
- click browse
4. on the bottom park of the zp_administrators table, you will find your username, delete it.
5. login to yourgallery.com/zp-core
6. you can now create new user again.

Hope this help!

Sorry, but how do I login in my mySQL client????

Please ask your host.

I must reset username and password of zenphoto, not username and password of database. Ok? For this, must I execute instruction that you tell me over?

andcubis: yes the instruction above will delete the username and password for zenphoto that you've created earlier. You have to ask your web host how to login to mysql client.

it is all ok!!!!!! I use phpMyAdmin and it's ok with these instructions!!!!
Thanks!!!!!!!
