Yes, wp_head() is in the header.php

It is not a free theme, I have purchased the theme. That’s why you can not find it.

I looked at the code for the theme and these lines are not included in header for the blog page.

JS:
wp-content/plugins/crayon-syntax-highlighter/js/jquery-1.7.min.js?ver=1.6.2
wp-content/plugins/crayon-syntax-highlighter/js/crayon.js?ver=1.6.2
wp-content/plugins/crayon-syntax-highlighter/js/jquery.popup.js?ver=1.6.2

CSS:
wp-content/plugins/crayon-syntax-highlighter/css/style.css?ver=1.6.2
wp-content/plugins/crayon-syntax-highlighter/themes/twilight/twilight.css?ver=1.6.2

After I included these lines of code in the header, everything worked as it should.

Yes, have have installed latest version (1.6)

Should work.

add_menu_page("Manage News", "Manage News", "manage_news_admin", "include_core");
add_submenu_page("manage_news_admin", "News", "Manage", "manage_news_admin", "include_core");

Don’t show in menu.

add_submenu_page("manage_news_admin", "News", "", "manage_news_admin", "include_core");
