Hi, I have the same issue. I am aware that I can navigate to Dashboard > Forums > Settings > Members admin page and edit the "Custom Authorization URLs:" option and write there /lostpassword/ . I am using "theme my login" plugin and the lost password link should be: domainname.com/lostpassword/ . I navigate and fill that link in the Custom Authorization section in wpforo as you described here, but still, when I click "lost password" link, the system shows me the Wpforo's "lost password" page instead of my original lost password page so my users can not retrieve their passwords. It redirects to this page: "domainname.com/community/?wpforo=lostpassword" instead of "domainname.com/lostpassword/". Doing this does not override the wpforo's lost password page. I even tried to retrieve a password using the page which wpforo brings. Even I try that, when a user writes their username or email to that page which wpforo brings and then click the submit button, the page redirects to domainname.com/lostpassword/ (which it should redirect at the first place when I click the "lost password" link) and this page shows a completely blank page. If I disable the wpforo plugin, everything works normal. What am I missing here? I also delete the cache before checking... Doing this tweak in settings as you described, does not work properly. Can you help me about this issue?

("Giriş Yap" means "Sign In")
By the way, I wonder if it is possible to use "wpforo" only instead of "Theme My Login" plugin for "sign up" and "sign in" in my website. But I need to put the sign up and sign in links in the meain menu too because my site is not only a forum, it is an online courses website so the users sign up or buy a video training too, so the forum is only a part of the website. I used the "theme my login" plugin just to make a custom sign up page rather than using the usual wordpress sign up page which I don't like.
