How to allow potentially unsafe HTML in Kayako Help Center articles
By default, Kayako is configured to block unsafe HTML tags and attributes, to ensure that your customers can safely browse your knowledge base. This may affect the way the browser renders the content, i.e., it may be displayed incorrectly or not displayed at all.
You can disable this default setting by allowing display of unsafe content:
- In the admin panel, click the Security menu.
- Under Security, select the Security policies menu.
- Go to Help Center content
- Check Allow potentially unsafe HTML in Help Center articles
Warning: this change allows potentially malicious code to be executed when users open an article in a browser.
