I need to assign more than one author to the same post, and I've found out a couple of ideas:
- using 'Author' category with authors as subcategories: it's fine, but then i have to render 'normal' categories and 'author' categories in separate ways. It's probably feasible but it looks messy.
- Co-Authors Plus plugin: it looks perfect but when I try to activate it I get this error:
Fatal error: Call to undefined function wp_set_post_terms() in /web/htdocs/www.ilcontesto.org/home/wp-content/plugins/co-authors-plus/co-authors.php on line 282
Plugin site: http://wordpress.org/extend/plugins/co-authors-plus/
What am I supposed to do to fix this issue?
My wordpress version: 2.7.1.
Thanks in advance!
