Fullaby

How do I set Fullaby, especially this: define(SQLLOG, 'CHANGME');        //Table (NOT DATABASE) used by image board
What do I type in this setting?

First, you need to have a MySQL database available. That is just the table of the database, it can be pretty much anything, as long as it isn't the same as another board you'd want to install.

And Futallaby is old shit, use Wakaba instead.
