Within a thread, how do you order the posts so #1 is first and #55 is 55th when you click on the thread?

 

The only setting I can find that might be causing this for you is:

Thread Display Mode
Here you can choose the display mode for threads. For a full explanation of the modes, please view this help page.


To get there:

1. Click the User CP link in the dark orange bar below the forum and thread title.
2. Click the Edit Options link in the left navigation bar.
3. Scroll about half way down the page and find Thread Display Mode.
4. Make sure linear is selected.
