try resetting your permalinks

The documentation for permalinks says the problem could be with the htaccess file but the instructions to get to it to delete and recreate it don’t match what I find in my “Manage” tab. How do I find it? Thanks.

what I would do
delete .htaccess
open Notepad or equivalent and save empty file as .htaccess.txt
upload to root of wordpress – rename to just .htaccess – chmod 666
go to your admin and set to desired permalinks – save
chmod .htaccess to 644 for security
