I switched from all in one seo to headspace and now my homepage page title isnt showing up.
It worked fine in the all in one seo plugin. any ideas?
This is the code currently in my template for page titles.

<title><?php if (is_home () ) { bloginfo('name'); }
elseif ( is_category() ) { single_cat_title(); echo ' - ' ; bloginfo('name'); }
elseif (is_single() ) { single_post_title();}
elseif (is_page() ) { single_post_title();}
else { wp_title('',true); } ?></title>

THANKS!
