Cannot access BBpress Support with my WordPress login

This might not the perfect place for the question but I don’t know where else to post.

I’m trying to access BBpress Support forum but I cannot login. When I press login, it says that I’m already logged in(just like I am now) but as long as I’m on the Support page, I appear as Anonymous and cannot post. If I go on any other WordPress pages I do appear as logged in already.

Any ideas? Thanks in advance.
