Are you on AEM 6.3? It is known Issue!!
An actual failure may occur if the Destination field is empty. In earlier versions of AEM this field was pre-populated.
If the field is populated, the error still will appear, but the operations are completed.
Use one of the following Workarounds:
- Move/rename the page and discard the error message (ensure the Destination field is set)
- Move/rename the page in CRX/de
- Move/rename the page in Touch UI
