I am using WPLMS Modern 1.2. Currently on the site, anyone (logged in or not) can view user profiles by clicking on 'course reviews'. If you click a username in the review you are then redirected to the user page and can view all user activity, badges, etc.
All usernames and emails are public and exposed.
I tried to find the menu option discussed in (https://wplms.io/support/forums/topic/hide-activities-tab-course-page/) but these options do NOT appear in the theme setting menu (see attached screenshot).
Please help as soon as possible.
Please make sure if you are using wplms_modern 1.2 then your default wplms theme and plugins should not be 2.x
So if you have already updated your default theme and plugins then please update your modern theme to 2.0.6.1 version otherwise ignore it.
In the topic you referred to, user wanted to hide activity tab and the option was introduced in 2.x versions only.
However to hide user profile visibility go to wp-admin->wplms->buddypress->single user profile view, refer:
