Hi, Alain.

1. First of all you removed JomSocial toolbar menu - it's used for components internal navigation. Removing it will cause redirect issues.
So please, recreate JomSocial toolbar menu with type "jomsocial" and recreate all menu items in this structure:

Profile
|— Change Profile Picture
|— Change Profile Video
|— Edit Profile
|— Edit Details
|— Privacy
|— Preferences
|— Customize My Page
Friends
|— Show All
|— Search
|— Advanced Search
|— Invite Friends
|— Request Sent
|— Pending my approval

2. You have menu misconfiguration. You should have ONE JomSocial frontpage menu item set to PUBLIC - you may place it in hidden menu (menu not displayed on your site). This was so MANY times explained on forum.

JomSocial menu items doesn't have OWN menu item ID but inherit it from JomSocial home menu item. If you set this item for registered - you'll experience issue like one you reported here. It should be always public. You may just hide elements on JS homepage.

Also if you want to have displayed JomSocial menu items in your main menu then you should create menu items as menu aliases and point to certain menu items in JomSocial toolbar menu.

Your issue is caused by "Professionnel Santé " menu item from menu "main menu" set for REGISTERED only.

Thank you Michal.

This is very good help. It solved my problem but I have a minor question. Can we move or add some menu to the toolbar and display it somewhere else ? In my case in the header location.

Can we hide or disable some items of the menu without affecting the behavior and induice bugs?
