Parsing either these URLs gives an empty post:

• https://en.wikipedia.org/wiki/Line-oriented_programming_language
• https://web.archive.org/web/20171112175252/https://en.wikipedia.org/wiki/Line-oriented_programming_language

I've seen this happen with other Wikipedia links as well, but not enough of them to assume all of them fail.

Will update this issue if I recognise a pattern in the failing links.
