Could not find a unique URI for this element Suddenly, I can't add any entry to a structure.
When I try to save a record, I've got "Could not find a unique URI for this element“. Although, the slug is perfectly valid and unique, but whatever I type in the slug field, same message "Could not find a unique URI for this element". I only got a couple of entries in this structure, so I could not have possibly hit the  'maxSlugIncrement' limit…
Thanks for your help.
The Uri of each element must be unique but if your Uri format is something that might not render a unique string you'll receive the error you are facing with.

As soon as you include some unique identifier like { id } or { slug } into your sections uri it will work again. Right now you can only save an entry if the field value is unique
