Basically Atahualpa causes post-titles in different languages to appear on the site at the same time.
Deleting the Atahualpa post options "Body Title Single Pages" and "Body Title Multi Post Pages" temporarily solves the problem. The entries are recreated on the next edit of that post though.
I'm using Atahualpa & qtranslate on an educational website, any help would be appreciated.
I figure it could just be an Atahualpa theme option but couldn't find it yet.
I'm using all the latest versions of Wordpress, Atahualpa and qtranslate.
Here's a screenshot showing the Atahualpa post options that cause the problem.
