Thanks for trying that, @mikael.
Please could you try this?
- Quit Local.
- Open the Finder.
- Hold down the alt/option key on your keyboard and click “Go” from the menu bar while the Finder is active.
- Choose “Library”. (Only visible when alt/option is held down.)
- Navigate to Application Support → Local.
- Right-click the file named
sites.json
and choose “Duplicate” to create a backup. - Edit the original file named
sites.json
(notsites copy.json
) in an IDE or text editor such as VS Code. - Using the find and replace feature of your editor, find all occurrences of “8.0.35” and replace them with “8.0.16”. No other edits to the file are needed.
- Open Local and try to start your sites.
If you see further errors please feel free to share screenshots or logs.
