Never mind, I was a silly panda. I forgot to add the Chibifurs_ part of the database name...
Thank you for being patient with me. It means the world.
I see, no worries I am just glad to see it work for you. Lemme know if you get any questions.
And regarding your last question, yes it can work even if you have users on your forum already, but you wont be able to sync forum users into your adoptables site. The trick here is to go to phpmyadmin and change the auto_increment ID to be identical from your adoptables and forum's table prefix.users. The User ID must match from one database to another.
