Archive Pages, JSON+LD, Description

I found a bug in plugins\schema-and-structured-data-for-wp\output\output.php, line 4078. You use $cat variable, but need to use $cat_term. In this case $cat_description will be always ” for archive pages.

$cat_description =  '';
if ( $category_id > 0 ) {
  $cat_term = get_term( $category_id );
  if ( is_object( $cat_term ) && ! empty( $cat_term ) ) {
    $cat_description = isset( $cat->description ) ? wp_strip_all_tags( $cat->description ) : '';
  }
}

the correct code

$cat_description =  '';
if ( $category_id > 0 ) {
  $cat_term = get_term( $category_id );
  if ( is_object( $cat_term ) && ! empty( $cat_term ) ) {
    $cat_description = isset( $cat_term->description ) ? wp_strip_all_tags( $cat_term->description ) : '';
  }
}
