bbPress.org

In my case I tried to install this version using my laptop, under Firefox web browser and could not login or sometimes even finish the installation due to cookies problems.

I check Tools>Options>Privacy>Show Cookies… and my site was not there.

I then tried to add the site manually and the problem did not solved.

I deleted the /forum/ folder and the bb_ tables from the MySQL database and uploaded the bbForum again. This time I used my desktop and checked the cookies first. My site’s cookies were registered and the installation went smooth and the forum is operational.

Hopefully this would help somebody.
