"Why is SoSH only showing 1 post of a thread and a list of posts below it?"

If SoSH is only showing the first post of a thread while the bottom says, "Posts in this topic" and shows a list of who has posted in the thread but isn't showing the material from those posts, do the following:

1. Click on the "Options" dropdown, which is at the right side of the thread topic.
2. Select "Switch to Standard".

Your SoSH should be fixed.
