Mar 30, 2026 — Create custom error pages in SIA

You can now design your SIA error pages. A new user interface in Enterprise Center (Policies > Error Pages) lets you do the following:

  • Define the supported languages and the default language of your error pages.
  • Create custom text that explains why the error occurred and who the user should contact for assistance.
  • Define the appearance of all content and elements on the page. You can define the font, font color, style, and background of page headers, text, and action buttons.

To learn more, see Customize error pages.
