When entering category settings Oh, no! The page does not exist or is a private page is displayed

I try to create a category, and then I can’t enter the category Settings page, and it says Oh, no! The page does not exist or is a private page.

Hey @FunnySmile,

Can you replicate the error ? also, are you an admin or a mod ?

Yes, I am the administrator. In the end, I had no choice but to restore the previous database.

I noticed that when I created the category, his address was not the default address of discourse creation, but the URL address with special symbols
