Thank you for your answer.
In the Dashboard > System Logs tab, 6 pieces of information
3x Reporting prohibited
The report was rejected (Mailer-Daemon@MY_HOSTING.com) by the "BAN LIST SYSTEM" filter
and
3x API Error (403)
Unable to create new ticket :Report prohibited: Mailer-Daemon@MY_HOSTING.com This Help Topic is only available to authorized users
So nothing important or dangerous
In the Dashboard > Audit Logs tab, you can't see anything, the page won't load. You can see the header and footer but without the "middle". It's a bit strange.
In the Dashboard > Information tab, I only have 1 piece of information
"cgi.fix_pathinfo" > "1" is recommended if AJAX is not working
