It seems that there is a bug on easydiscuss "profile page" menu link. Indeed, everytime a user clics on this link, and then decide to move on the last posts of the user, he is redirected on the homepage (and should move on the concerned post/discussion, so the link must redirect on something that doesn't exists). Anyway when I use the classic "Forum" menu link, and then move on the profile of the user (and only using that path) there is no problem.
The problem seems to be in the URL with the /menuitem/profile... path. I precize that I use URL rewriting (dont know if there is any link).
This is quite complicated so I made a video to make sure you understand.
What should I do to solve this problem, because it is quite an issue !
Im here for any request, and hope you will find where is the problem, thanks !
