***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.
Any help is greatly appreciated.
