Replace comma separator from terms list output

Here is a code snippet to replace the comma character between single post terms:

add_filter( 'generate_term_separator', function() {
    return '-';
} );

The above code will replace the comma with a -. You can also remove it altogether by removing the - in the return statement.

add_filter( 'generate_term_separator', function() {
    return '';
} );

Or replace it with a space:

add_filter( 'generate_term_separator', function() {
    return ' ';
} );

Here is how to replace the comma with a space inside a WP Show Posts card:

add_filter( 'wpsp_term_separator', function() {
    return ' ';
} );

Finally, here is how to do it if your terms are located inside a header element as a template tag:

add_filter( 'generate_page_hero_terms_separator', function() {
    return ' ';
} );
