That is just some sloppy code, it should check for the property first.

It shouldn’t cause any problems, though, so what is the “offline” issue you’re referring to?

Thanks for reassuring me, the ‘offline’ means that it’s still only on my computer under Xampp.
I’m not sure if it would be different once it’s uploaded to my provider. But as I understand it, it’s nothing to worry about.
