Issue

  • The attempted efforts to modify the configuration of a page don't work.

Environment

  • Liferay DXP 7.3

Resolution

  • One reason for this error could be that (at least one of the) the friendly URL(s) for the page does not start with a forward slash ('/').
  • Already since Liferay DXP 7.0, friendly URLs for pages need to start with a slash. Otherwise there's a warning: "Please enter a friendly URL that begins with a slash."
  • Please review the friendly URLs to make sure the first characters is a forward slash.
