Hi @Fariborzzz, it seems this PR is changing a lot more file than intended. Could you fix that?

Hi @Fariborzzz, it seems this PR is changing a lot more file than intended. Could you fix that?

the case seems to be that you have by default some different file permissions which yielded in all project changes, for next time is better to set your git to ignore file permissions before committing changes

git config core.fileMode false

@Fariborzzz shall be fixed now 🐰

Thank you @SkafteNicki and @Borda. Sure, I'll set up git ignore for my next commits 😃!
This was the first commit, hope the next ones are smoother.
