On this forum, there is no second page. Some threads have disappeared over the last few weeks, so there must be a page two and three etc.

Besides a brain, am I missing something?

 

same here - but the 'show posts' choice went to 2 weeks on mine. change back to all and they re-appear

 

If you change "show posts" to "beginning" there are 135 pages

 

You can change the setting to show how far back you want to see in your settings. Then you have to constantly mess with them.
