I've noticed that after a short time, threads are no longer showing up in the various sections. Some sections are worse than others.

The 05-09 V8 section I just noticed is shrinking. Now it's only two pages but barely. And the sub forums under that section the threads go away even quicker.

WTF?

 

at the bottom (after the actual threads end) check the third box ("from the" part) in the display options to see how long date wise it will show threads. i had this problem too and the box had 'last day' selected; changed it to 'last week' and the threads returned

 

Ooooh I didn't see that. I had a feeling there was a setting controlling this.

 

That explains it.
