I know it’s been a long time since this question was posted…
Here’s the answer anyway
The plugin should create a table in the database called wp_httpbl_log (change the wp_ to your database prefix) when you activate the log function – strange that the description still says you have to do it manually
If it doesn’t, then add this table using your phpMyadmin manager (Apache server) – name as above – number of columns = 6
Here’s a full setup guide including instructions for the database table

It should create the table. But sometimes this is prevented by the limitations for the MySQL user used for WordPress.
p.s. Mike, thanks for your guide!
