I'm sorry if this is a known issue. I tried searching the existing threads, but I could have missed it (I may be in over my head).
The theme looks great, but I've got one problem. I use the WP archive and category sidebar widgets. When I activate Atahulalpa v3(.1.8? - the most recent one anyway) and try to pull up a list of posts from either (a category or a month) I get the following error message:
"Fatal error: Call to undefined function: is_last_post() in ... /wp-content/themes/atahualpa/archive.php on line 32"
