harukatruong on "JSJ Code Highlight error?"

I have some problem when using JSJ Code Highlight. My page display warning: call_user_func_array() expects parameter 1 to be a valid callback, class 'JSJCodeHighlight' does not have a method 'footer_actions' in /home/u713626669/public_html/wp-includes/plugin.php on line 429. So how can I fix it?
Thanks for advance.
