In D7, whenever I go into Administration » Structure » Menus
The menu item for My account always shows "My account (disabled)"
Tried clicking the "ENABLED" check box and save, it will say changes saved but the check box will revert to being unchecked.
Why is it always disabled? Although the My account menu item does still appear under the user menu block when viewed in front end.
This has been going on since March 15, 2011 and it still appears in latest release of Drupal. I was unable to find another issue queue with this issue.
