Hi,
I had the same problem and what I did was manually writing the DB with phpmyadmin. I inserted one record in each table and now it's working. However, I've found that even if you're logged on, the first time you try to answer a thread it sends you to the login page, then it works fine.
Keep up the good work, it's a nice contribution. :thumbsup:
