Thanks Matt. The Open Adminer link does take me to a page in the Adminer web app at localhost showing the same local DB name and username as my site. I tried to zip and import the SQL files from app/sql but this didn’t work in Adminer. It looks like the recommended way to import a site now is generally to zip up the entire directory, so perhaps I should try this again this time ensuring to rename the root folder/site name to something different, and maybe that will get rid of the issue.
