Hi Guys, I have the same problem, really annoying and cannot get the Website Main Title to appear even though I have selected 'Force Rewrites' and also got this: %%sitename%% | %%title%% in the Posts and Pages title template.
I have tried editing the header.php file and even tried the following settings:
<title><?php wp_title(''); ?></title>
<title><?php wp_title(); ?><?php bloginfo('name'); ?></title>
<title><?php wp_title(); ?></title>
and still not joy, Disable SEO and it works great, enable SEO and it doesn't!?
Any ideas?
