[Joomla Error] Another menu with the same parent has this alias

Solution:  Empty out the Trash.  See below the steps to empty out your menu item trash:

1.  Log in to your Joomla 1.6 administrator backend.

2.  Click on ‘Menu’, ‘Menu Manager’, Change tab to ‘Menu Items’

3.  From the filter drop downs, ‘Select State’ = Trash

4.  Using the checkboxes on the side to select the menu items you want to delete permanently.

5.  Click on the button ‘Empty Trash’.  In my case, I would select ‘Joomla Tips’ menu item and ‘Empty Trash’ it.

Now go to your menu items and you should be able to create a new menu item with the same name as the one you deleted
