vpoliteI'm using MyDomain as my host. I built a off Child Theme of 2011. When I activate it on the host, I get this error "Fatal error: Call to undefined function is_multi_author() in /usr/local/pem/vhosts/263254/webspace/siteapps/152554/htdocs/wp-content/themes/twentyeleven/functions.php on line 583". The Child theme works though? The styling is there, but the content for the static pages does not appear? What is the error? How do I fix it?
