Good day.
For some reason, a certain file does not want to be added to git. I make changes to the file, but this file does not get into the commit.
it is not in gitignor.
Which way to look to solve this problem?

Answer 1

figured out
[3:28]
it was because of the submodule in newdyatkovo
[3:29]
fatal: Pathspec 'newdyatkovo/scripts/site.js' is in submodule 'newdyatkovo'
[3:30]
did this:
git config -f . git/config --remove-section submodule.newdyatkovo
git config -f .gitmodules --remove-section submodule.newdyatkovo
git rm --cached newdyatkovo
git add newdyatkovo/scripts/site.js
