Category description after posts

Hmm, not easily, but do-able.

First, hide the current description:

.page-header .taxonomy-description {
    display: none;
}

Then add it in:

add_action( 'generate_after_main_content', 'tu_tax_description_after_content' );
function tu_tax_description_after_content() {
    if ( ! is_archive() ) {
        return;
    }

    $term_description = term_description();
    if ( ! empty( $term_description ) ) {
        printf( '<div class="taxonomy-description">%s</div>', $term_description );
    }
}

You'll likely have to style it with some CSS, but that should get you started :)

That works :-) Thanks for your help!

You're welcome :)
