Hi,
BuddyPress provide you a custom link to reach logged in user’s profile.

In the WordPress menu, if you add a link like this

http://yoursite.com/members/me/

It will be converted to the logged user’s profile. For example, if a user with ‘admin’ username is logged, it will point to

http://yoursite.com/members/admin/

You will need to replace http://yoursite.com/members with the members directory url.

You can use the above link for the other urls too. Just replace the url up to member’s profile the above dynamic slug.

For Recent Visitor, Please open the recent visitors tab and look for the url in the location bar. Now, replace the part until member’s username with the above and use it in the custom link option.
You can repeat the same for any link.
