The same errors appear multiple times: backslash instead of a double-quote mark, two consecutive "f" characters deleted. I suspect this to be a software problem, not a copyediting problem. It also references figures that are missing.
So I suspect someone hit publish but their latex-to-wordpress plugin is broken, or somesuch. That's just a guess.
It's not too uncommon for websites to just end up as blank slates with noscript, I just never expect it to be because they literally told the browser to hide it and somehow scripts tell the browser to nevermind that and show it.
