Made it easier, looked in bitrix/wizards)))

Answer 2

There are 2 options:
1. Ctrl + z (unlikely)
2. Analyze files manually (read view).

Answer 3

You can get it from the browser cache (the file will be in the cache if the cache is not disabled manually), but if the file has not been changed, I have exited the situation several times.
