🤷🏽‍♀️ Cannot see some posts!

There are some posts by my friends and others throughout the different discussion threads that I cannot see to read. Only the person's name, a blank profile pic and other basic info show. Why is this happening and how can I change it. I am new here and want to interact with others, but I can't if I cannot read their posts. 💁🏽‍♀️
