I was using the 2011 theme, then installed the 'News' theme - on activation I got this message:
Fatal error: Call to undefined function wp_get_theme() in /home/pnisbet/public_html/seocontent.co/wp-content/themes/news/library/functions/utility.php on line 119
This line appears to be:
$theme = wp_get_theme( get_template(), get_theme_root( get_template_directory() ) );
Now I cannot do anything - I can see my dashboard, but clicking on a link either gives me a blank screen or the same message.
Must I carry out a complete reinstall, and will I lose my content?
