My forum got crazy

[Lean721]

Hi!

Something very strange is happening in my forum. When we enter all users, it shows us as if we were another user, I don't know if you understand. For example, I am logged in as the user "Claudio", but "Hello Matias" appears above. If I enter any section of the forum, my username changes again and it says "Hello Sergio". The forum changes my user depending the URL.

Help please!
Thanks!

That is classic evidence of the host running some sort of caching that doesn't understand user context.

Ask the host to turn off Varnish - if they don't understand, ask what caching they have.
