I just installed 1.8.1 Graphene theme, the theme is very cool!!
As seen in http://fadjartn.com, but when I go into the dashboard, and choose Graphene Options http://fadjartn.com/wp-admin/themes.php?page=graphene_options, it says:
Fatal error: Call to undefined function get_current_screen () in / home / public_html / fadjartn.com / wp-content / themes / graphene / includes / theme-head.php on line 256
Please help me.. :'(
