If you go to your archive and to a forum and look at the links for the threads, you see this:

http://www.rarewarecentral.com/forums/archive/t-627.html

But, it should be something like this:

http://www.rarewarecentral.com/forums/archive/index.php/t-627.html

However, if you enter that corrected link, you get redirected back to the first archive page.

Try disabling your plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

PHP Code:

define('DISABLE_HOOKS', true);
