Text not showing on certain websites

#1

For several months now, there’s been two sister sites that when I try to open text on mobile or desktop (either clicking on feed or the Shift + Enter shortcut) it’s showing only a title of an earlier post or advertisement or something else, usually a paragraph long plus a title. It’s not showing the feed.
The two sister sites are www.thekitchn.com and www.apartmenttherapy.com.

Anyone have any ideas?
