I need a very simple forum for the website I'm planning to build on Processwire. I tried to run Apeisa's Discussion module, but when I clicked on "reply" or "another reply" links, I get a "404 Page not found" message although I can see my messages added when I click on the "submit" button. I could not go further. As a beginner in PHP and other programming languages, I find it hard to find out what could be wrong.
So I read a little further and found some people mentioned about the integration of FluxBB or SMF, but there was no instruction how to do that. Is it possible to elaborate a little on this and guide me through?
