I installed and ran the plugin "Better Search Replace" with the urls in the secure note and it came back with:
DRY RUN: 51 tables were searched, 0 cells were found that need to be updated, and 0 changes were made.
I also deleted the portfolio image and re-uploaded it and still doing the same thing. I am using GoDaddy managed wordpress hosting and they give an automated 1 click staging staging environment. So no, we did not migrate, but maybe the GoDaddy staging environment seems like a migration to wordpress?
