In 3.6.4, where are fields to enter keywords and meta descript
 

In atahualpa wordpress theme version 3.6.4, when creating a new post, the entry fields to enter keywords and meta description are missing. Where did they go? The ability to enter tags is still there but keyword entry field and meta description are gone.

My guess is you're referring to custom fields?

When in the Post editing screen, look to the top right corner of the page and find "Screen Options". In there, you'll find numerous things to check/uncheck, to clutter/unclutter your editing sessions. Check custom fields and see if this is right. Otherwise you might have additional plugins which will add other checkable items.
