Link "My Workbench" no longer visible I've always used the Workbench and the Workbench Moderation modules, but recently, the link "My Workbench" in the admin menu has disappeared...   

I tried reinstalling the module several times, but no luck there. And all the permissions are checked and double checked, so nothing wrong there.

What else could be the issue?
In order to have it appear in the admin menu.
You need to give access to:

"Use the administration pages and help"

Because the My Workbench link is child of admin:
/admin/workbench
