Hmmmm - that's three problems that have 'disappeared' for no apparent reason in recent days.
Rob557 - JSON files are 'unix' files (lines endings are LF only), sounds like you used an editor that wants 'dos' files (lines endings are CRLF), e.g. Notepad.
I use Notepad++, this is what I see - unix file on the left, dos file on the right.
