Joomla 1.6- Category Same Alias Error Message

by Elaine on April 13, 2011

Following along the same path as my last post about Joomla 1.6 same alias error for a menu item, this is regarding categories.  I created and deleted a parent category named ‘Test’.    I later recreated another category also named ‘Test’ and after saving it the second time around I got an error message:

Could not save data. Error: Another category with the same parent category has the same alias.

I knew what to do this time because I had almost the same error message last time with the Menu Manager Menu Item alias.  All you have to do is look in the ‘Trash’ed categories in the Category Manager and empty the trash.    This is how you emtpy the Trash categories from your Joomla 1.6 website:

1.  Login to your Joomla 1.6 administrator backend.

2.  Click on ‘Content’, ‘Category Manager’.

3.  Use the dropdown filters – ‘Select State’ = Trash

4.  Use the checkbox to select the categories that were deleted.

5.  Click on the top button ‘Empty Trash’.

That’s it.  Switch your state back to ‘Select State’ = Select State and you will see all your published, unpublished, active, and trashed categories again.   If you try to create the category again with the same name ‘Test’ you will have no error messages.

I get this for multiple Items that I try to “empty” :

“Delete not allowed for category [Category Name Here] . 1 item is assigned to this category.”

I created a post for you and it’s here. I also see that you found a solution to ignore errors when deleting categories. If you chose this option, you might have a lot of articles that do not have a home (orphaned and not assigned to any category).
thanks for your visit,

Extentions > Plugin Manager
click on > Content – Joomla
Make sure it is enabled
in the “Basic Options” on the right of the screen you will see: “check category deletion”
Click No
Now you should be able to delete …. (worked for me)
