Group discussion isn't showing up on desktop view! Need help.

I joined a few different groups yesterday and they all were working fine for most of the day.

Then today when I went into those same groups the discussion portion wasn't showing up .

It keeps spinning as to load, but it doesn't show up no matter how much I wait.

I accessed those same groups in the mobile version of FB m.facebook and the discussion wall showed up just fine. But in desktop view it's not showing up.

How do I fix this?
