Hello everyone. The top menu with the tabs registration, login, account, and so on has disappeared. Once I deleted the forum (it worked fine then) and tested other plugins. Then I installed wpforo again and this time the top menu is not shown. In the Wordpress settings, user registration is allowed. WPforo settings are standard, I didn't change anything. I don't know what to do.
P.S. I apologize if it is not clear, the language is not native, the translation was made using Google translator.
We are lucky that wpforo has another sidebar. Everything is normal there, links to registration and login are in place.
Please navigate to Dashboard to Appearance > Menus admin page. Select the wpForo Navigation, then check/enable it for wpForo Menu location.
Also please read wpForo Menu Doc:

Thank you very much for your help!
