When I change the database password in the hosting service control panel, PowerGallery can not connect to the database. I get errors that look like they're from MySQL.
So, I changed the database password back, and now I see the PowerGallery Admin logon screen. It still doesn't let me in.
The password contains no special characters, so no quotations. Just alphanumeric, including some capital letters.
So, the SQL database password is fine. PowerGallery can connect to it, apparently. But there's password to get into the Admin gallery that needs to be reset or recovered or something.
