I was having a problem with my site title repeating itself, and then I found this old thread that helped me out alot: http://wordpress.org/support/topic/wordpress-seo-yoast-duplicate-site-title?replies=17
As said in support I used replaced the code <title><?php wp_title(''); ?></title> in my header php and I stopped getting a repeated site title; YES! But something happened, a minor issue it seems. What happened is that part of my site title has blended leaked into my theme. The last guy that responded on the link I supplied you said that he fixed the problem, but he did not say how he did it. Please help me, my website is: http://www.creativesolvibrations.com
Sorry, I do not know how to use the link and code option here.
