I have an issue with a site running on WP 3.3 where when we make the permalink anything by "/%post_id%/%postname%/", the archive pages break and become 404s.
After some research, I came to understand why from a performance perspective, this is not a good practice, so I tried the suggested alternatives: "/%year%/%postname%/" and "/%post_id%/%postname%/"
Both suggestions worked, except that only with the post_id one, did archive urls become "/date/2012/11/" for example, and were found. Under any other permalink suggestion, they just were "/2012/11/" for example, and produced 404s.
Now the question is why does WP only put the word "date" in when the permalink is "/%post_id%/%postname%/"?
I figure it works with the "date" parts because it matches to "/date/%year%/%month%/".
As note, category and tag urls came out as usual and worked: example "/category/news" and "/tag/advice/".
