The plugin works fine; alternative you can use a own function to replace the bloginf() to your CDN-Url; Example:

replace the url in content:

// replace content for CDN
if ( !function_exists('fb_add_static_content_url') ) { function fb_add_static_content_url($content) { if ( is_admin() ) // eigentlich überflüssig return $content; $wpurl = get_bloginfo('wpurl'); $search = array( $wpurl . '/wp-content/images/', $wpurl . '/wp-content/download/', ); $replace = array( 'http://cdn1.bueltge.de/', 'http://cdn2.bueltge.de/', ); return str_replace( $search, $replace, $content ); } add_filter( he_content', 'fb_add_static_content_url' );
}

replace stylesheet_directoy and others:

// replace for CDN
if ( !function_exists('fb_add_static_wpurl') ) { function fb_add_static_wpurl($info, $show) { if ( is_admin() ) return $info; $keys = array( 'url', 'wpurl', 'stylesheet_url', 'stylesheet_directory', emplate_url', emplate_directory', ); if ( in_array( $show, $keys ) ) { $wpurl = get_bloginfo('wpurl'); $search = array( $wpurl . '/wp-content/images/', $wpurl . '/wp-content/download/', $wpurl . '/wp-content/themes/', $wpurl . '/wp-content/plugins/', ); $replace = array( 'http://cdn1.bueltge.de/', 'http://cdn2.bueltge.de/', 'http://cdn3.bueltge.de/', 'http://cdn3.bueltge.de/', ); return str_replace( $search, $replace, $info ); } else { return $info; } } add_filter( 'bloginfo_url', 'fb_add_static_wpurl', 9999, 2 );
}

replace the template_directory and other:

function fb_add_static_stylesheet_uri($uri) { if ( is_admin() ) return $uri; $wpurl = get_bloginfo('wpurl'); $search = array( $wpurl . '/wp-content/images/', $wpurl . '/wp-content/download/', $wpurl . '/wp-content/themes/', $wpurl . '/wp-content/plugins/', ); $replace = array( 'http://cdn1.bueltge.de/', 'http://cdn2.bueltge.de/', 'http://cdn3.bueltge.de/', 'http://cdn3.bueltge.de/', ); return str_replace( $search, $replace, $uri );
}
add_filter ( emplate_directory_uri', 'fb_add_static_stylesheet_uri' );
add_filter ( 'stylesheet_uri', 'fb_add_static_stylesheet_uri' );
add_filter ( 'stylesheet_directory_uri', 'fb_add_static_stylesheet_uri' );
