Does anyone have any idea how to get these working again, please?
Try using a different browser to access your account and see how things behave there.
I've noticed that several FB things that used to work fine have gone goofy within the last few weeks for me when using Safari 9.1.3 in Mavericks 10.9.5.
When trying Firefox 59.0.2 most things work as expected.

Thanks for that Patrick. I will certainly try Firefox.

The best way of controlling facebook is to download FB Purity for your specific browser. It's free and works wonders on Mac OS (not iOS).
