Then i can only guess that some PLUGIN is doing that. Disable one by one and see from where the issue come.
I try to flush the permaling, re save the permalink option, regenerate the htaccess, desactivate all plugin except wpforo but i still don't have a clue.
As i said in my first post i already done all the "classic stuff" before posting here :/
Delete the /community/ page.
Check the Shortcode in /forum/ page. Maybe it is not posted correctly.
did you create 2 pages with the forum shortcode?
/forum/
wpf-default wpft-topic wpf-guest wpfu-group-4 wpf-theme-2022 wpf-is_standalone-0 wpf-boardid-0 is_wpforo_page-1 is_wpforo_url-1 is_wpforo_shortcode_page-0
/community/
wpf-default wpft-forum wpf-guest wpfu-group-4 wpf-theme-2022 wpf-is_standalone-0 wpf-boardid-0 is_wpforo_page-1 is_wpforo_url-0 is_wpforo_shortcode_page-1

Thank you so much both of you.
I find the problem thank of your answer.
I had two page with the wpforo shortcode as tutrix find.
I have a community page and a forum page.
The problem was that the forum page was in draft... so obviously only the admin could read it.
Thank you again for your time to help me 🤗
