If you are talking about the title separator, here is the solution.
To change the separator in all pages. add this PHP snippet –
add_filter( 'document_title_separator', 'whitedot_title_separator' );
function whitedot_title_separator( $sep ) {
$sep = "|";
return $sep;
}
To change the separator in only on your homepage(static). add this PHP snippet –
add_filter( 'document_title_separator', 'whitedot_home_title_separator' );
function whitedot_home_title_separator( $sep ) {
if ( is_front_page() ) {
$sep = "|";
}
return $sep;
}
To change the separator in only the blog home page. add this PHP snippet –
add_filter( 'document_title_separator', 'whitedot_blog_title_separator' );
function whitedot_blog_title_separator( $sep ) {
if ( is_home() ) {
$sep = "|";
}
return $sep;
}
To change the separator in the default blog page(front blog page), add this PHP snippet –
add_filter( 'document_title_separator', 'whitedot_front_blog_title_separator' );
function whitedot_front_blog_title_separator( $sep ) {
if ( is_front_page() && is_home() ) {
$sep = "|";
}
return $sep;
}
If you want to completly remove the separator, just leave the double quote blank like this $sep = "";
