I did the installation and everything was normal, a few hours later nothing loading related to the forum. I click on members, the forum that was created, and even the forum menu, but nothing is loading. Sorry for the English, google translator.
You have done wrong configuration setting the forum as home page. You should not set the main forum page as a home. You should create another page with wpForo shortcode and set the second page as a home page. Please read the documentation again: https://wpforo.com/docs/wpforo-v2/getting-started/forum-page/set-forum-on-home-page/
Also, make sure the forum page is not deleted. You should see the page ID in wpForo > Boards admin page.
I'd also recommend reset permalinks by clicking [Update options] in Dashboard > Settings > Permalinks admin page.
It worked following the steps in this link, thank you very much.
