    I’ve just installed the Responsive plugin on my site, but it doesn’t appear to be working. The General Settings page is displaying the following message:

    Warning: call_user_func() [function.call-user-func]: First argument is expected to be a valid callback in /home/wmpc/public_html/wp-admin/includes/template.php on line 1119

    Do you have any ideas what could be causing the issue?

    Thanks
    Greg
