I recently installed WordPress, and I'm having a problem with permalinks. In the admin section under Options->Permalinks I should be able to change the permalink structure from the default to "date and name based" or "numeric", but when I click "Update permalink structure" it switches back to the default. The note comes up that says "permalink structure updated," so it seems to think it worked.
Is there a way to fix this so that I can change the permalinks? Do I need to reinstall and start over? I'm skeptical that that would fix it, since it never worked properly to begin with.
