First, I tried to create categories and forums through the Admin Control Panel, tried to view it but nothing was updated on the forum. I tried several times until I cleared the cache and wala! There are all my entries for categories and forums. I am now trying to delete all of them except for one of each them. How do you delete them? I went through the admin panel again, deleted it but nothing happens. Cleared cache and everything. What am I doing wrong? I am using the latest Apache, the latest JForum and the default HSQLDB.
