Secure Knowledge Base Links

Under Settings > Basic, you can choose to Force SSL links so that your knowledge base will load using "https" rather than "http". SSL links ensure that all data passed between the visitor and the site is encrypted. 

All KnowledgeOwl subdomains can use SSL links and have the option to Force SSL (http links will redirect to https). However, if you have a private domain, you will need to add your site SSL certification, chain, and key to make SSL links works.
