I use the Evidens theme on my blog (http://ragnarockmusic.com/). In the header php file it has "<title><?php bloginfo('name'); ?><?php wp_title(); ?></title>" for the titles of pages. As you can see, if you go to a single post it shows the blog name, a "»" tag, and the title of the post. However, I don't want to » tag. How do I remove it?
