***I accidentally posted this twice earlier and it seems those two posts got locked and no one can help me so I have recreated this***
Okay I have a weird one today. On the main page on my website, dotTech.org, whenever I try to view page that lists 2008 posts I get a 404 error. However this does not happen if I view pages of categories. And I know for sure the posts have not been deleted.
See for yourself what I mean:
http://dottech.org/page/27 --- Last post on this page is on Jan 1 2009
http://dottech.org/page/28 --- First post on this page should be from 2008
Now see that this does not happen if I view a specific category:
http://dottech.org/category/gotdreviews/
http://dottech.org/category/gotdreviews/page/13 --- Shows posts from 2008
Any help is greatly appreciated.
