OK. Let’s see what we can figure out.
Some follow-up questions:
- Would you be able to provide some screenshots that show the paths and issues you are having?
- Are both the live and staging site running TYPO3 v12, or is it just the staging site.
- Do you have a development environment on your computer or are you performing the upgrade directly on the staging environment on the server?
- Are you using a Composer-based or legacy installation?
- Have you tried all the suggestions mentioned in the other thread?
Best wishes
Mathias
