Please refer the steps below
- Please ensure that you have the Destination panel Expanded in Lightroom import window
- Also make sure that they are getting imported to a Valid location(see the same in destination panel)
- You must have Operating system level Read/Write permissions for your import Source and Destination.
Thanks for this. However, I neglected to mention that the program worked great for the preceding 3 years and I suddenly started getting this error message.
This problem can occur when we accidentally collapse the Destination panel or change the location to something invalid.
