Example of a warning on the "Admin home" page

Example of a warning on the Admin home page

  1. Session entropy length: Your PHP session.entropy_length setting is too small. Set it to at least 16 in your php.ini to ensure that generated session IDs are random and unpredictable enough. You can learn more about this advisory on the OWASP session management cheatsheet.

  2. Noreply email address: If the system email address is empty or a malformed email address, you are asked to check and correct it in the system mail address setting.
