Hi,

When I’ve installed the forum in “forum setup”, and then it say: “the forum is correctly installed”. Then, when you are going to create a group and mark “allow forum” it gives you an error. Also at the top menu, there is a link called “Forum”, I click and redirect me to “www.blablabla.com/forum/” and appear like “there’s nothing in the page”, an error.

Did you change Settings > Permalinks to other than default setting? mod_rewrite must be enabled in your server.
