I have bbpress properly set up, and it worked well, except when clicking the user’s profile page, there is no sidebar with logged-in widget.

Actually the sidebar was under user’s profile page. See this image.

How to fix this?
I checked the source code, looks like the user profile page don’t have a ‘.et_right_sidebar’ class for its ‘left-area’, seems I need to change its template page? How?

I am still a beginner to understand template code. Any good resources to better understand WP codebase?

However, other forum page or topic page are fine with sidebar, like this.

@dingzj

its tricky to solve issues in premium themes.

first contact your theme authors support.

see if its only that themes issue

see if its a plugin issue , deactivate every plugin but bbPress if that solves it reactivate each one and try to pinpoint the one causing the issue.

if you havent created a bbpress.php file see if creating one fixes the issue.
