I have multiple layers. Like: /en/knowledge-base/faq-slug/ /en/knowledge-base/faq-slug/faq-page-title but twill generates the faq-page-title slug as follows: /en/faq-slug/knowledge-base/faq-page-title It switches faq-slug and knowledge-base for the two under Frequently asked questions Any idea why? Maybe something is going wrong when using an empty permalinkbase? protected $permalinkBase = '';
