Saying that you changed "few lines" is not at all useful: if you
hope to get any help from the list, you'll have to share the *exact*
changes you made each time and the full XML configuration that
resulted from them.

Again, saying that you added "few lines" is not helpful because we
have no idea what those lines look like, so it's simply impossible
for anyone to figure out the root cause of the error message you're
seeing. Please share the *exact* changes you made.
