Symptoms
The header background color for the page that the user receives when blocked by an ACL is always white. Changing the color under Advanced Customization attribute "Page Header Settings" changes the color of, for example, the Logon Page but not the acl deny page.
Impact
The customization of the color done via the Advanced Customization is not reflected in the ACL deny page
Workaround
This issue is Cosmetic and has no workaround.
Fix Information
After the fix, the ACL deny page correctly reflects the customizations which were done via Advanced Customization Dialog
