Can't update this collection error

Backlight 4 & 5 Support

I am creating a new album. Originally I was able to upload the photos using LR Publisher. I rearranged the photos in LR and tried to republish and get the message

“Can’t update this collection.
The rendition could not be created. Please ensure that the original file name is accessible, especially when stored on external or network storage.”

The page on the website is Kay Celebration of Life - Photographs-Now, Inc.

Any ideas what I have done wrong?

Thanks

The error implies that the original file may not be accessible. Check to make sure that the drive containing the images is plugged in and turned on.
