If your buddypress child theme or customized parent theme does not work properly, in otherwords does you title tag output “[Blogname] – Blog” then use the code below to remedy the error.

Whats happening is if you use bp_title_tag() is will output the default string as seen above. If you lean towards using the WordPress conditional tags to test the pages, WordPress will see the BuddyPress pages as normal static pages.

Using bp_get_title_tag we can test to see if its a WordPress page or a BuddyPress page and use the appropriate title tag.

<title><?php
if ( is_home() ) { bloginfo('name'); echo '&nbsp;|&nbsp;'; bloginfo('description'); }
elseif ( is_search() ) { bloginfo('name'); echo '&nbsp;|&nbsp;'; _e('Search Results'); }
elseif ( is_author() ) { bloginfo('name'); echo '&nbsp;|&nbsp;'; _e('Author Archives'); }
elseif ( is_single() ) { bloginfo('name'); echo '&nbsp;|&nbsp;'; wp_title(''); }

// Entering the buddypress tags
elseif ( is_page() ) {

 $page_title = rtrim(ltrim(bp_get_page_title()));

 if ( $page_title == "[INSETRT YOUR WP_TITLE HERE] — Blog" ) { bloginfo('name'); echo '&nbsp;|&nbsp;'; wp_title('');}
 else{ bp_page_title(); }
}
elseif ( is_category() ) { bloginfo('name'); echo '&nbsp;|&nbsp;'; _e('Archive'); echo '&nbsp;|&nbsp;'; single_cat_title(); }
elseif ( is_month() ) {  bloginfo('name'); echo '&nbsp;|&nbsp;'; _e('Archive'); echo '&nbsp;|&nbsp;'; the_time('F'); }
elseif (function_exists('is_tag')) { if ( is_tag() ) { bloginfo('name'); echo '&nbsp;|&nbsp;'; _e('Tag Archive'); echo '&nbsp;|&nbsp;';  single_tag_title("", true); } }
else {  } ?></title>
