Just updated our Jomsocial to its latest version and noticed that the Toolbar URLs are not working at all. We tried to fix the links by editing it inside the menu manager but after changing it menu item type and saving it, still didn't fix the issue in the front end.
This's happening because you've JomSocial menu items, in other menus as well, but unfortunately it was designed bassicaly for internal navigation. So I suggest to disable all menu items which are pointing to jomsocial toolbar, in other menus then JomSocial toolbar menu, and it'll solve the problem.
When we upgraded to the latest version the Jomsocial Toolbar, and the Jomsocial menu items from other menus are appearing in the back end with an unpublished status and under menu item type says "Component 'com_community' does not exist", but the items are still available in the front end, but the links to them are not working. If we try to delete them, is not possible.
Also, the Jomsocial toolbar is not working at all, when you log in to the site, the profile is not reachable.
We read the documentation you just posted and still having the problem.
