Something seems wrong with that to me.
Coindesk works just perfect, it might be an ad or something similar that was "started" by an adware or any other software in your PC which is a common thing.
I use adblock/ublock to block most of the ads that are shown in the website even though it can't block all of them.
Stay safe.
I get a wordpress site as well. My cache is cleared, so this is definitely a live version of coindesk. It looks like some sort of misconfiguration with WordPress.
website fixed. returned to normal coindesk. might have been some sort of maintenance/new feature...
