Right, we got that. Your fancy permalinks aren't working on the new site.
What steps have you taken to diagnose this on the new site?
- Have you tried deactivating all of your plugins
- Switching to the Twenty Eleven theme
- Confirmed that mod_rewrite is configured and that your directory on your Apache configuration contains something like this
Options FollowSymLinks -Indexes
- Switched to the non-fancy permalinks
?p=123 just to see that something else is not going on?
For permalinks to work, you need
mod_rewrite enabled and functioning. Can you test that?
Let us know and provide some information and us volunteers may be able to assist you.
